摘要：

Three-dimensional turbulent flows and heat transfer in a rectangular channel with longitudinal vortex generators on one wall and rib-roughness elements on the other wall have been modeled by the k-epsilon model and law of the wall and computed. Rectangular winglets have been used as vortex generators. Results show that the combined effect of rib-roughness and vortex generators can enhance the average Nusselt number by nearly 450%.
