| Abstract:The regenerator impacting jet numeric calculation model was established, and the 3D simulation analysis was carried out. The influence rule of plenum spacing on the flow field of regenerator body was studied, and its influence on Stirling engine performance was also analyzed. Taking a certain type of Stirling engine as the research object, test verification was carried out with respect to the simulation results, which showed that the simulation results coincided well with the test results. The research results offer reference for the improvement of Stirling engine performance. |
