Determination of Mass Transfer Coefficient for Bubble Column (Air-Water System) Using Image Processing

This research suggests a simple system to study the hydrodynamics in a bubble column reactor and measuring gas-liquid specific interfacial area a, individual mass transfer coefficient k,gas holdup ε , flow regime, bubble size distribution, coalescence of bubbles, and bubble rising velocity for a single bubble by using image processing techniques.G Images and movies were taken by a digital camera and then analyzed in MATLABR2008a to extract the required data need to obtain the design parameters for bubble columns from special equations.
