MEASUREMENT OF ACTUAL GAS VELOCITY IN TWO-PHASE FLOW USING HIGH SPEED VIDEO AND IMAGE PROCESSING
SINOPSIS
For many years, the modelling of two-phase, gas-liquid flows has been severely hindered by actual measurements of phase velocities and interfacial parameters (e.g., interfacial area, interfacial shear). Such information is crucial for the development of reliable two-phase flow codes and correlations. Recent advances in high speed photography and video imaging, coupled with significant development of image processing techniques and software, have opened new opportunities in flow visualization and measurement techniques. This report represents the results of measured gas-phase velocity in two-phase flow. The measurements were obtained using high speed video images and several image processing software. The results agreed within 20−25% with the values using the "no-slip" velocity approach.
