Abstract

Computational analysis of turbulent fluid flow and forced convective heat transfer by forward- facing step with a corrugated wall is performed. The method used for solving the governing equation is the finite element. The SIMPLE algorithm has been useful to study the effect on heat transfer and fluid flow of the Reynolds number (5000 to 2000 range) and the corrugated parameters. The corrugated height and width were (1, 2, 3, 4, and 5 mm) and (10, 15, 20, and 40 mm) respectively. The result observed a significant enhance in the heat transfer by using the corrugated wall and reach up to 50% at corrugated height = 4mm and width = 20mm. Although the rise in the average skin friction coefficient on the same parameter exceeded 53%. Moreover, as the corrugated length and width increase the Nusselt number and skin friction factor increased until reach a particle point and start to decrease again.
