摘要：
The influence of Dufour effect on entropy generation in double diffusive convection is numerically investigated in this paper. The dimensionless total entropy generation is evaluated as a function of: the buoyancy ratio N, a parameter characterising the solutal buoyancy forces by report to the thermal ones the Dufour parameter K-F, a parameter characterising the influence of the diffusion-thermo effect. the thermal Grashof number. More details of the investigation is focused for the special case when N = -1.
