Numerical simulation of heat and fluid flow has been performed to estimate the value of heat transfer coefficient between the working gas and walls 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 compared with the value calculated by the correlating equation reported up to now.
