ABSTRACT
This paper presents an intensive review of heat exchangers
with twisted tape inserts. The main motive of this work to find
out the best possible efficient heat exchanger configuration.
Heat exchanger with wire coil inserts has highest heat
exchanging capability. Double counter twist inserts
outperformed other configuration when thermohydraullic
performance is considered.
INTRODUCTION
In this era of industrialization and modernization, energy play
vital role in the development of nation. Solar air heater[1-2] ,
solar water heater[3-4] and heat exchanger are the main
components of thermal energy systems. Heat exchangers are
key components of refrigeration[5-7] and cryogenic
systems[8]. Efficient heat exchangers are the need of today
world, as the fossil fuels depleted with very fast rate[9] .
A Review of Heat transfer features of diverse inserts.
Twisted Tape inserts
The Twisted Tape inserts fir introduced by Sir Whitham et
al. There are many kinds of Twisted Tape inserts used for heat
transfer enhancement factor.
Inserts play important role as turbulence promoters in the heat
exchangers .The different types of the inserts used yet is
shown in Table.1.
There are number techniques used in heat exchanger for
creating turbulence in flow. A lot of study has been done by
number of researchers for creating turbulence in flow field of
heat exchanger.
Inserts are modified as per previous study in augmentation of
thermo-hydraulic performance. Passive techniques are
always in keen interest as these are economic. Inserts also
give compactness to heat exchangers. The inserts the strips of
mertals with different geometrical configuration. The types of
twisted tapes are as follows:
1.Tapes with twist ratio
2. Perforated Tapes
3. Cut Tapes
4.Doble twist tapes
5.Dimple tapes
6.Coupling
7.V-cut tapes
8.V-finned
9.Tappered
10.Clock wise twisted
11.NonUniform tapes
12.Continious spaced
13.Trapaziodial
14.Quadrapule cut
15.U cut
16.Multiple quadrapule
17.Double v- ribbed
18. Perforated and helical etc.
The description of tapes are presented in Table.1 given below.

RESULT AND DISCUSSION
The Thermo hydraulic performance parameter (η) defined
below by eq 1.
η =𝑁𝑢/𝑁𝑢𝑠
(𝐹
𝐹𝑠)1/3
S – Smooth tube
Fig 2: shows the graph of different geometries of inserts used
for air .The graph of thermal performance factor for air tell that
efficiency diminish with growing values of Reynold number in
each case. The thermal performance factor of non uniform coil
and twisted tape lies in the range of 2.5 – 2.7 and other are
below this range so the better thermal performance factor is for
non uniform coil and twisted tape.
Hence, thermo hydraulic efficiency for inserts used has better
performance .
CONCLUSIONS
This review paper emphasize on different TT.
Thus we selected diverse TT layouts for two working fluids
first is air and second is water, and we got different result of
thermal performance factor, nusselt number, friction factor. We
got thermal performance factor more than unity for maximum
geometry of twisted tape inserts of air as a working fluid & got
thermal performance factor more than unity for each geometry
of twisted tape inserts of water as a working fluid. The
maximum thermal performance factor for water is 2.3 for
trapezoidal cut twisted tape (TCT) and for air maximum
thermal performance factor is 2.7 for DI coil and twisted tape
(DCTT).
