A suitable k-epsilon model for CFD simulation of pump-around jet mixing tank with moderate jet reynolds number

A suitable k-epsilon model for CFD simulation of pump-around jet mixing tank with moderate jet reynolds number

This paper presents the appropriate turbulence model for predicting the overall mixing time inside an open 45° inclined side entry pump-around jet mixing tank with moderate jet Reynolds number of about 17,515. The model was carefully developed by using appropriate hexahedral grid arrangement and pro...
