Abstract

The present work consists of a numerical study of turbulent incompressible two-dimensional flow with heat transfer in a corrugated channel using a computer code. The k-ε model is used for turbulence modeling. The governing continuity, momentum and energy equations are written in two-dimensional Cartesian coordinate system and are numerically solved using finite volume method. This study concerns the effect of the Reynolds number based on the hydraulic diameter and the thermal behavior of the hydraulic channel. The thermal and dynamic fields of the flow in the corrugated channel were obtained in a satisfactory manner. Satisfactory results about velocity distributions, pressure and temperature allowed us to understand the behavior of the Nusselt number and friction coefficient along the walls of corrugated channel. A comparison between the numerical and experimental results shows a good agreement.
