摘　　要：采用整体求解法求解了控制气流与多层套环之间的耦合传热问题,计算得到了控制气流参量随时间的变化情况,以及迷宫形多层导热套环的温度在不同时间点的分布情况。将计算结果与试验结果进行了比较,分析了传热对流体压强、温度等气流参量的影响。The conjugate heat transfer between control flow and multi-layer lantern-rings was solved by using unitary computation approach. Change of control flow parameter vs time and temperature distribution of multi-layer lantern-rings at different time step were obtained. The calculation results were compared with test results, and effect of heat transfer on pressure, temperature and flow parameter of gas was analyzed.
