摘　　要：气动力/热与结构热响应多场耦合问题涉及物理因素众多且不可简单分割。本文对该耦合问题涉及的各物理场特点与耦合关系进行了研究,从基本物理特点和方程出发,研究了物理场间的耦合关系,并对一直沿用的多物理场耦合关系提出了新的观点与看法。以此为基础,研究获得了气动力/热与结构热响应多场耦合问题的数据流程,提出了针对该耦合问题特有的时间-空间耦合概念,并对其耦合策略与方法进行了深入探讨,为进一步开展相关计算研究工作奠定了理论基础。Based on the physical characteristics and governing equations,the relationships and characteristics between different physical fields of Multi-disciplinary coupling problem have been deeply studied,and some new ideas and opinions against the ever-lasting traditional coupling relationship were put forward.The time-space coupling concept specific for this problem was herein first proposed.For the space coupling,the surface coupling,body coupling and surface-body coupling were proposed.And for the time coupling,the time full coupling,time loose coupling and time correction coupling were then proposed.As a result,the calculation data flow and coupling solution strategy for aerothermoelasticity were formed.
