2LIF technique mass transfer measurement in bubble column

Mass transfer is an important process in chemical engineering and processing engineering, it has attracted researchers’ great attention. It is of great interest to have mass transfer detail or its local distribution in multiphase flow. even ignore the laser sheet variation and energy reabsorption in the path, multiple interface caused reflection, distortion break the uniformity of the illumination, which is hard to know the new intensity distribution and this may still can give qualitative results to show how mass transport revolute, but it is impossible to implement the principle of the technique to have quantitative knowledge about this,  in this project, a new experiment technique based on 2LIF (dual-laser induced fluorescence) is developed to overcome the  issues to get mass transfer detail.
