The characteristics of turbulent flow and mass transfer in divergent channels of rectangular cross-section were experinlentally investigated and the typical effects of main flow and the secondary flow on mass transfer were discussed. Sherwood number S_<hx>, could be suitably expressed by Reynolds number R_<ex>, and acceleration parameter K. Sherwood numbers S_<hx>, in the entrance region of mass concentration were proportional to R_<ex,>^<0.83> for every diver-gent angle in the present experiment. The velocity profiles in the upper region were recognized as a composite structure consisting of those for the inner and outer layers. but it was difficult to predict the velocity profiles in the lower region with the plane jet profile.
