Abstract
Numerical simulation of heat and fluid flow has been performed to estimate the value of heat transfer coefficient between the working gas and the wall in oscillatory flows. Transient two-dimensional equations of continuity, momentum and energy were solved utilizing a TVD scheme. A physical model of a simple circular tube in which the wall temperature is constant was used for the numerical simulation. In this study, the value of local heat transfer coefficient in oscillatory flows was clarified by analyzing the numerical result of the two dimensional simulation and the heat exchanged between the working gas and the wall were analyzed.
