中文摘要：
气热耦合计算有助于高温透平叶片热流和温度分布的准确预估。在气热耦合计算中,流体区域和固体区域可能采用不同的网格形式和不同的求解器;此外,在大涡模拟等大规模计算中,流体区域和固体区域的耦合需要在并行环境中进行。因此,需要发展在不同求解区域支持不同的网格形式和求解器,并且适用于大规模并行计算环境的高效气热耦合方法。本文发展了并行计算环境中的高效气热耦合方法,其流体域和固体域之间的耦合通过高效的并行数据交换来实现,其对求解器类型和网格形式以及负载分配没有限制。数值算例验证了本文气热耦合方法在并行计筛环境中的高效性和灵活性。
英文摘要：
Accurate prediction of the wall temperature and heat flux distributions requires the conjugate heat transfer which couples the fluid solver and the solid solver.In the conjugate simulation,different types of solver and mesh may be used in the fluid domain and the solid domain.Also in large-scale computation like Large Eddy Simulation the computation and the coupling should be conducted in the parallel environment.As a result,it is necessary to develop a parallel coupling framework which simultaneously supports various types of mesh and solver.In this work an efficient parallel coupling methodology is developed in which the coupling between different domains is achieved by the coupler based parallel data transfer.It applies to all types of solver and mesh type,also it has no limit on the load balance.Numerical results verify the efficiency and flexibility of current coupling method in the parallel environment.
