“…The values of R when there is no gas bubble and when gas bubble is present are compared. The existence of bubble in water resulted in a higher value of R as indicated in (5) compared to when no bubble is present as indicated in (3). Light experienced less attenuation when gas bubble is present.…”

“…Many researchers have published their result using the optical sensor in order to monitor the movement of gas, liquid, and solid. Idroas et al [5] have successfully applied an optical tomography system for particle sizing identification using sample of beads and irregular shaped nut. Rzasa and Plaskowski [6] have presented gas bubbles measurement using an optical tomography system in a vertical aeration column.…”

This paper presents the results of concentration profiles for gas bubble flow in a vertical pipeline containing contaminated water using an optical tomography system. The concentration profiles for the bubble flow quantities are investigated under five different flows conditions, a single bubble, double bubbles, 25% of air opening, 50% of air opening, and 100% of air opening flow rates where a valve is used to control the gas flow in the vertical pipeline. The system is aided by the independent component analysis (ICA) algorithm to reconstruct the concentration profiles of the liquid-gas flow. The behaviour of the gas bubbles was investigated in contaminated water in which the water sample was prepared by adding 25 mL of colour ingredients to 3 liters of pure water. The result shows that the application of ICA has enabled the system to detect the presence of gas bubbles in contaminated water. This information provides vital information on the flow inside the pipe and hence could be very significant in increasing the efficiency of the process industries.

“…SFT methods has the common problem of low sensitivity in the center of the region of interest. As consequence, the reconstructed image result often suffers image distortion, artifact and blurry edges which could not precisely visualize a stratified multiphase flow regime [14].…”
