To aim the enhancement of heat transfer on the cylinder wall we have begun CFD simulation in the expansion space. Axi-symmetrical simulation was done with a moving displacer and simulated mass inflow calculated from an isothermal model. Thermal condition on the wall is assumed adiabatic. We present the results of its first step –– a study of flow pattern. It is shown that the inflow from the heater generates a strong vortex covering about 80% of cylinder wall in the transfer process. It delays rapidly by the expansion.
