Study on mass transfer of turbulent air flow sweeping liquid surface

Different forces in interface of gas-liquid in the process of turbulent air flow sweeping liquid surface were analyzed. Characteristics of flowing section were done and Prandtl mixing length theory was used, the principle of turbulent flow mass transfer in the process of turbulent air flow sweeping liquid surface was studied. Effect of Reynolds number, gas flow structure and Prandtl mixing length on the mass transfer were analyzed. It indicated that the turbulent flow mass diffusion coefficient and mass transfer coefficient were involved with the state of gas flow and was affected by gas flow structure. The results are in favor of lucubrate study and engineering application of mass transfer in gas-liquid interface.
