A vortex element method based on Biot-Savalt law and the core spreading model was extended to analysis for unsteady heat transfer. Discrete heat elements were introduced into the flow field close to a wall surface in addition to nascent vortex elements. In this study, unsteady flow and heat transfer were calculated around a circular cylinder to a uniform flow in the range of Re=200∿1000, and Pr=0.71. From the result of the present calculation, the mechanism of unsteady heat transfer in the separated flow region of the cylinder was clarified.
