Heat transfer enhancement from surfaces with cavities

Three dimensional single and multiple cavity flows with heat transfer enhancement are to be investigated. Cavities are composed of spherical dimples with various depths and dimple distances. They are placed on a flat, heat conducting channel. When fluid flows over the cavities, its flow characteristics such as pressure, temperature, velocity profiles, and turbulent shear stresses change. This study investigates the relationship of these characteristics to the heat transferring phenomena on the surface. The results of the computational study of the impact of single concave cavity on the aerodynamic resistance and heat transfer coefficient compared with experimental data are presented.
