Abstract

Average heat transfer in a turbulent flow on a plate with a system of double-cavity diffuser-type dimples is studied experimentally. The regime of turbulent flow almost reproduces the airflow in a cooling system of a turbine blade. Physical and numerical simulation of flow in a double-cavity diffuser-type dimple is performed. Two self-organizing vortices emerging in the dimple were documented. They provide continuous mass transfer between the dimple and the flow. Numerical simulation results agree well with the physical experiment.

Abstract

Nonisothermal flow past a circular cylinder of the fluid with spherical gas inclusions is studied. It has been established that as the volume concentration of the dispersed phase increases, the drag force of the cylinder reduces and its heat transfer with the medium decreases.
