Abstract :
This paper present the result of a study the behaviour of asymmetrical annular two-phase gas-liquid flow at different gas and liquid flow rate by using several thresholding techniques. The behaviour of annular flow is analysed base on liquid film thickness which is calculated after thresholding process. Thresholding techniques are applied on the images which are captured by Electrical Capacitance Tomography (ECT) in vertical upward flow. The results at the end of this report show which thresholding techniques that able to yield good thresholding images and show the liquid film thickness of annular two-phase flow at different gas and liquid flow rate.
