A numerical calculation has been carried out to investigate the mixed convection heat transfer in inclined rectangular ducts with wall transpiration. The vorticity-velocity method is employed to solve the governing equations. The present paper particularly addresses the effects of the independent parameters, namely, mixed convection parameter , modified Rayleigh number Ra*, wall Reynolds number Rew and aspect ratio J. The predicted results show that either wall injection or wall suction has a considerable impact on the flow structure and heat transfer performance. Additionally, it was found that for injection case (Re(w) < 0), the Nusselt number Nu is retarded with an increase in the wall Reynolds number Rew, but the trend is reverse for the suction flow (Re(w) > 0).
