This study investigates the three-dimensional (3D) mixed convection heat transfer within an air-cooled inclined cavity. The simulations are performed using the finite volume method associated with the SIMPLEC algorithm to process the pressure–velocity coupling. The results of this study are presented in terms of flow structures, 3D streamlines, isotherms, temperature iso-surfaces, and the heat transfer rate for different combinations of thermal and geometrical governing parameters. It was concluded that the cavity inclination might be a support control parameter of the heat transfer performance. The maximum heat exchange is encountered at the inclination angle of 35° for mixed and natural convection-dominating flow regimes.

摘要

This study investigates the three-dimensional (3D) mixed convection heat transfer within an air-cooled inclined cavity. The simulations are performed using the finite volume method associated with the SIMPLEC algorithm to process the pressure–velocity coupling. The results of this study are presented in terms of flow structures, 3D streamlines, isotherms, temperature iso-surfaces, and the heat transfer rate for different combinations of thermal and geometrical governing parameters. It was concluded that the cavity inclination might be a support control parameter of the heat transfer performance. The maximum heat exchange is encountered at the inclination angle of 35° for mixed and natural convection-dominating flow regimes.
