Combined heat transfer enhancement by mist and rod insertion in a back-step flow

Abstract

Heat transfer experiments were conducted to clarify the effect of combined heat transfer enhancement in the downstream region of a backward- facing step by means of a small amount of mist and insertion of a circular rod. The rod in the duct was located in four kinds of vertical position. In the results of the heat transfer experiment, a large effect of heat transfer enhancement was obtained at the case of a rod position was equal to step height.
