Heat transfer has been investigated on the end surface of cylinder enhanced by an annular jet from a channel installed in the displacer. The heat flux was estimated from heat generation in the foil heaters of which each temperature was controlled with CTA circuit individually. Conventionally, the heat exchanger capillary tube and so on are provided in order to increase the heat transfer in the compression and expansion process. However, by the introduction of the capillary tube the flow resistance is increased and the work is reduced. The purpose of this paper is to investigate experimentally the possibility of heat transfer enhancement by causing the proper flow to the high and low temperature space. In the Cylinder a displacer with the annular channel is placed. Annular jet is driven by reciprocating displacer. As a result, the heat transfer is enhanced when the displacer descents or stops near the bottom dead center. High heat transfer is restricted to stagnation region.
