| Abstract: | Mass-flow-distribution inside heater-pipe has important lntluence on the efficiency of Stiring engine, for various structural combinations of heater and regenerator, 3D simulation via FLUENT software is carried out for flow conditions inside them, which is helpful to modify former unreasonable design. In addition, an optimum structural scheme is purposed on the consideration of technology. This research offers important theoretical foundation for structure improvement and production of heater and regenerator. |
