Résumé

The convective heat transfer characteristics in a periodic two-dimensional corrugated channel are investigated numerically using finite element methods. Experiments were also performed for heat transfer analysis and the results were compared with the numerical predictions. Studies were carried out for air, for a corrugation angle of 20°, and for a channel height equal to the corrugation height such that all corrugation peaks lie in an in-phase arrangement with thermal boundary conditions of uniform heat flux. It was found that both the heat transfer coefficient and the pressure drop for the corrugated ducts are in good agreement with experimental results.
