PROBLEM STATEMENT

In industries, tomography is used to describe the characteristic of components flows using methods that are non-invasive as well as to determine the type of fluid (gas, liquid, solid) is flowing through a pipeline. As one of electrical process tomography techniques, Electromagnetic Tomography (EMT) also known as Magnetic Induction Tomography (MIT) has the unique advantage that it employs magnetic inductance measurements to extract tomographic data related to permeability and conductivity distributions [1]. The main elements of the tomographic systems of EMT are split into three main sub-systems (sensor array, conditioning electronics and host computer) [2-3]. These element functions were design for pipeline inspection. However, this technique is involves the magnetic behavior where the flux line and sensitivity distribution in the cross section of the pipe are invisible. Other than that, the development of EMT also requires lots of experimental and researches that cost of money and time only to get best method and instrument to get best pixel on image reconstruction. So, the best practice to start is through simulation modelling in computer. The suitable software is by using COMSOL Multiphysics as a tool to analysis and produces the distribution magnetic field in cross-section of pipe. This software set the numerical simulation where is conducted through finite element method and some reconstructed images are presented without any hardware attached. In order to achieve this purpose, the following objectives have been derived.OBJECTIVES The objectives of this project are:1. To analysis the best method and instruments in Electromagnetic Tomography (EMT) for pipeline imaging.2. To design and develop a simulation modelling of the distribution magnetic field inside the pipeline using COMSOL Multiphysics. SCOPE OF STUDY1. The investigation of Electromagnetic Tomography (EMT) for pipeline imagine is limited to flux line & sensitivity distribution in the cross section of the pipe2. The simulation modelling is by using COMSOL Multiphysics with finite element method.\EXPECTED RESULTThis project is expected to develop simulation of imaging of the distribution magnetic field inside the pipeline by using COMSOL Multiphysics. From the simulation it is also able to get best method and instruments in EMT for pipeline imaging.REFERENCES[1] A J Peyton, Z Z Yu, G Lyon, S Al-Zeibak, J Ferreira, J Velez, F Linhares, A R Borges, H L Xiong, N H Saunders, M S Beck, Overview of electromagnetic inductance tomography: description of three different systems, Meas.
