Two Phase Flow By Using Electrical Tomography

Electrical Tomography has been widely used in the industry to obtain the cross sectional images. Three types of electrical tomography are being applied; Electrical Resistance Tomography (ERT), Electrical Capacitance Tomography (ECT) and Electrical Impedance Tomography (EIT). The aim of this project is to improve the performance of current flow rigs to enable bubble flow regime, to fabricate new sensor of ERT for data acquisition and to calculate the void fraction using the image processing techniques. ECT sensor is calibrated and studied but it is not fabricated for this project. Dual ERT sensor is designed and tested using data acquisition unit and software available in the laboratory. The ITS M3000 dual-modality provides information on the multiphase flow pattern, flow regime, composition and velocity. It produces conductivity and permittivity maps from multi-electrode sensors arranged around the pipe. Aside from using the Multi-Modal Tomography (MMTC) software, LCR meter can also be used to obtain data measurement result. However, this project only covers a part of ERT which are designing and fabricating the ERT prototype
