โฆ Synopsis
theoretical model is developed in order to predict the gas absorption rate during gas bubble formation and rise through a shallow liquid pool. The model takes a rather straightforward approach to the hydrodynamics of bubble formation and rise, allows for the general case of mass transfer with simultaneous (mn)th-order chemical reaction and includes a novel description of the age distribution of liquid elements at the gas-liquid interface. Model predictions are successfully verified with data from two typical industriallyimportant systems investigated in a laboratory foam column reactor.
