The water type Stirling engine is replacing the mechanical part that corresponds to the power piston and the displacer with a series of water. Therefore, the working gas is moist air, fundamentally. It is known that an output of the engine decreases, when the evaporation to the working gas from the water column surface is suppressed. In this study, the effect of evaporation and condensation of water on heat transfer in a circular pipe with oscillating flow was examined numerically. Such flow and heat transfer are observed in water Stirling engine. Calculation parameters were frequency, amplitude, temperatures of heating and cooling units. The effect of these parameters on heat transfer was declared.
