FLUID MACHINES

The centrifugal fan is a radial flow machine, which produces the necessary pressure to move gas by the centrifugal force built up inside the fan casing. The design of the fan blade has a primary influence on performance.

These types of fans are usually employed for ventilating duties requiring a somewhat higher delivery pressure than that available from axial fans.

CENTRIFUGAL FAN DEMONSTRATION UNIT - FM40

The axial fan produces gas flow by virtue of the momentum changes imparted across the rotary blades, parallel to the axis of rotation. Such fans are more suitable for higher flows at lower delivery pressures than their centrifugal counterparts. Comparison of the performance characteristics of the FM41 Axial Fan with those of the FM40 Centrifugal Fan thus provides an instructional exercise of valuable practical application.

AXIAL FAN DEMONSTRATION UNIT - FM41

Multi-stage compressors are used industrially for high pressure deliveries of gas flows or suction duties.

The kinetic energy imparted to the gas by the impeller rotation is converted into pressure energy, which progressively increases from stage to stage.

PUMPS - FM 50 SERIESCENTRIFUGAL PUMP DEMONSTRATION UNIT - FM50

Centrifugal pumps are often used together to enhance either the flow rate or the delivery pressure beyond that available from the single pump.

The unit is designed to demonstrate the operational advantages of parallel or series operation, depending on the required duty.

SERIES AND PARALLEL PUMPS DEMONSTRATION UNIT - FM51

The plunger or ram pump is a positive displacement pump and is used for pumping small quantities of liquid at high pressures. It is similar to a piston pump except that the sealing gland is at one end of the cylinder.

The reciprocating motion of the plunger gives an uneven flow, although the inclusion of a damping vessel can reduce this effect. Priming is unnecessary.

The gear pump is the most widely used of the positive action rotary pumps. Two gear wheels operate inside a casing; one is driven while the other rotates in mesh with it. The liquid is carried around in the space between consecutive teeth and then ejected as the teeth mesh.

The pump has no valves. It is a positive displacement pump and will deliver against high pressures. The output is a more even flow than that of a reciprocating pump. It is particularly suitable for high viscosity fluids.

COMPUTER CONTROLLED HEAT EXCHANGER SERVICE MODULE - HT30XC

The Armfield HT30XC Computer Controlled Heat Exchanger Module has played an important part in the development of computer controlled experiments over the internet described in a paper* published in the USA journal, Chemical Engineering Education and involving Cambridge (England) students use of equipment in Cambridge, Massachusetts.

This bench top computer controlled service unit enables the operation of the Armfield range of small-scale heat exchanger systems. It provides controlled cold water flow, bi-directional hot water flow and the instrumentation required to do a series of in-depth investigations into heat exchanger performance. The individual heat exchangers can be quickly changed over, to enable comparisons between different types of heat exchanger to be made. The HT30XC requires a personal computer with USB for the operator interface.

Educational software is provided for all Armfield heat exchangers. Included are drivers to enable other software applications to communicate with the HT30XC via the USB interface. Users can also write their own software typically in LabVIEW™, MatLab™, ‘C’, ‘C++’, Visual Basic™ among others, to remotely control the equipment, for example, over a Local Area Network (LAN) or even over the internet. The HT30XC is ideal for this, as it has been designed to shut down safely in the event of a communications failure. Once the heat exchanger has been installed and configured, the student does not need to be present with the equipment.

FIRE TESTING TECHNOLOGY

Ignitability, defined as the capability of a material of being ignited. The FTT1 Ignitability apparatus measures the minimum percentage of oxygen in a test atmosphere that is required to marginally support ignition / combustion. This percentage is referred to as the oxygen index. A higher oxygen index suggests a more fire resistant material. It is one of the most accurate and reproducible ignition tests.

NEW IGNITABILITY - FTT1

NEW SMOKE RELEASE - FTT3

NEW FLAME SPREAD- FTT2Life safety and means of escape dominate fire safety in buildings and are associated with the behaviour of materials under fire conditions. This means fire protection must be considered at the architectural and construction stages of a building project which involves an understanding of the reaction to fire behaviour of a material, or combination of materials.

The FTT series is designed to introduce students to the fundamental principles of measuring reaction to fire, exploring the concepts of ignition, flame spread, smoke production, heat release and toxicity.

The FTT2 Flame Spread tester is based on the FMVSS 302 standard, which is used in industry to specify the burn resistance requirements for materials used in the occupant compartments of motor vehicles (i.e. passenger cars, multipurpose passenger vehicles, trucks and buses).

The FTT2 enables the user to measure the distance a flame spreads along a material against time to determine the burning rate. A lower burning rate suggests a more fire resistant material.

The FTT3 Smoke release is a laboratory procedure for measuring and observing the relative amounts of smoke obscuration produced. The measurements are made in terms of the loss of light transmission through a collected volume of smoke produced under controlled, standardised conditions. The light absorption data are acquired by a user-friendly software tool and are plotted versus time. Two indexes, the maximum smoke produced and the smoke-density rating, are used to rate the material.

new

The FTT4 Bomb Calorimeter is an affordable high resolution isoperibolic temperature regulated oxygen bomb calorimeter with embedded control computer.

The bomb calorimeter is the most common device for measuring the heat of combustion or calorific value of a material, which can be solid and liquid specimen, such as coal, coke, petroleum and alcohol. With this apparatus a test specimen of specified mass is burned under standardised conditions. The heat of combustion determined under these conditions is calculated on the basis of the observed temperature rise while taking account of heat loss.

NEW FLAME SPREAD- FTT2

NEW BOMB CALORIMETER - FTT4 NEW HEAT RELEASE - FTT5The FTT5 Heat Release test enables the user to measure ignitability, mass loss rate and heat release and is a simplified version of the widely used Cone Calorimeter.

FTT5 enables the user to carry out thermal exposure studies, under the same precise exposure conditions as those used in the Cone Calorimeter, whilst visibly observing the time to ignition, specimen reaction and measuring the mass change. A flue containing a thermopile can also be added to the unit to measure heat release rate.

The FTT7 Cone Calorimeter is the most significant bench scale instrument in the field of fire testing because it measures important real fire properties of the material being tested under a variety of pre-set conditions. These measurements can be used directly by students / academics or they can be used as data for input into correlation or mathematical models used to predict fire development. Directly measured properties include:

• Time to ignition• Mass loss rates• Smoke release rates• Rate of heat release• Rates of release of toxic gas

The FTT6 Toxicity test explores the toxicity of the products of combustion in terms of small molecular species arising when a sample of a material is completely burnt in excess air. All combustion products are collected in a chamber and then analysed using colorimetric tubes to measure the concentrations of various toxic gases.

Wetted wall columns have proved valuable in determining mass transfer coefficients, essential in calculating the design of absorption towers. They serve as a basis from which correlations have been developed for packed towers.

In this case the absorption studied is that of oxygen from air into deoxygenated water, which is produced by sparging the water with nitrogen in a deoxygenating column. This is an example of absorption, which is liquid/film controlled; the liquid/film mass transfer coefficient can be determined at various mass flow rates of the water.

Biochemical Engineering is currently a growth area, attracting worldwide interest. Although many of the techniques and operations are common with Chemical Engineering, there are some important differences.

Armfield have introduced two products, BE1 and BE2, which together with CEU, give students an introduction and understanding of important Biochemical Engineering principles.

A batch enzyme reaction system that utilises the industrially important glucose isomerisation reaction, (converting glucose to fructose) catalysed by glucose isomerase.

The purpose of the unit is to demonstrate batch enzyme kinetics and enzyme characteristics. The reaction takes place inside a stirred vessel where the stirrer itself is a porous basket inside which the enzyme is immobilised.

A polarimeter device, which is integral to the unit, monitors the glucose and fructose concentrations with time.

BE2 aims to demonstrate the principles and practices of chromatography - an important operation for both small- scale analysis and large-scale production of biologics.

BE2 features two chromatography columns of variable bed height, which are fed by a peristaltic pump. An injection point enables samples to be introduced onto the column.

The unit has an on-line UV sensor for measuring protein concentration as it exits the column. BE2 is also equipped with a timer-controlled fraction collector. Size exclusion chromatography is the primary separation technique used for the demonstrations. Engineering principles, such as the effect of feed flow rate and bed height on process performance can be investigated.

DLM-1 Cross Flow Heat Exchanger

This cartridge demonstrates the function of a fan and radiator to cool water. The DLMX reservoir is filled with hot water, which is pumped through the heat exchanger. The inlet and outlet water temperatures are measured to demonstrate the cooling effect. The relationship between heat transfer and water flow rate can also be investigated.

DLM-2 Fluidised Bed

A highly visual demonstration of a fluidised bed. The onset of fluidisation can be demonstrated and the way the height of the bed varies with the flow rate. The pressure drop across the bed is measured, so the way the pressure varies before the onset of fluidisation and after fluidisation has occurred can be illustrated and compared to theory.

DLM-3 Orifice Plate

The use of an orifice plate to measure flow is demonstrated by measuring the pressure drop across a defined orifice. The geometry of the orifice is in accordance with standard industrial orifice flow meters.

DLM-4 Shell and Tube Heat Exchanger

This cartridge requires two DLMX base units*, one filled with hot water, and one filled with cold water. The inlet and outlet temperatures of both fluid streams are measured, enabling the heat transfer coefficient to be measured and an energy balance to be performed. The two flow rates can be individually varied and the flow direction through the shell can be easily changed. The internal geometry of the DLM-4 is based on industrial 2-1 shell and tube heat exchangers.

DLM-5 Tubular Heat Exchanger (tube in tube)

This cartridge requires two DLMX base units*, one filled with hot water and one filled with cold water. The inlet and outlet temperatures of both fluid streams are measured, enabling the heat transfer coefficient to be measured and an energy balance to be performed. Reversing the flow in the outer tube demonstrates the difference between co-current and counter-current operation.

DLM-6 Energy Losses in Hydraulic Systems

This cartridge simultaneously measures the pressure drop across a straight pipe, a smooth bend and a right angle bend. Each test section is of the same cross section and same path length, enabling meaningful comparisons to be made. The additional energy losses due to the geometry of the flow path can be clearly seen at different flow rates and the relationship to theory can be established.

DLM-7 Venturi System

The DLM-7 demonstrates the Bernoulli equation, showing how low pressure is generated in the throat of a venturi tube, and how this is affected by flow. The flow recovery is also demonstrated by measuring the total pressure drop across the module. The geometry of the venturi orifice is in accordance with standard industrial venturi flow meters, so the use of a venturi to measure flow can also be demonstrated.
