Turbulent Transfer Coefficients Model for Flows over Permeable Rough Surfaces
Краткое описание
This paper submits a wall region model of turbulent transfer coefficients for flows over a permeable rough surface. The model takes into account violation of the analogy between the transfer processes of heat and momentum in the vicinity of a rough wall. The results of friction and heat transfer computations both in boundary layers and pipe flows are compared with measurements for different types of roughness. In particular, results show that increases in the roughness height undertaken for heat transfer intensification can lead to the opposite effect for fluids with high Prandtl numbers.
