Using the multivision technique, a new void fraction measurement method was developed for bubble and slug flow in a small channel. The multivision system was developed to obtain images of the two-phase flow in two perpendicular directions. The obtained images were processed—using image segmentation, image subtraction, Canny edge detection, binarization, and hole filling—to extract the phase boundaries...
This work attempts to investigate the feasibility and potential of Capacitively Coupled Contactless Conductivity Detection (C4D) technique in the void fraction measurement of gas–liquid two-phase flow in millimeter-scale pipe and hence to propose a new void fraction measurement method based on C4D technique. A new C4D sensor is developed and a void fraction measurement system is constructed. As a...
