摘要: 低温风洞降温过程中，温度变化范围大，容易在结构内部引发较大热应力，影响设备运行安全。以中国空气动力研究与发展中心0.3m跨声速低温风洞扩散段为研究对象，基于流固热耦合方法，采用多物理场数据交换接口MpCCI，联合结构有限元软件Abaqus和计算流体动力学软件Fluent，建立扩散段的流固热耦合仿真模型，分析低温内流场的换热特性，计算低温风洞结构的温度及应力分布。通过低温风洞试验发现，流固热耦合仿真结果接近于实际的测量结果，能够准确反映低温风洞结构的热力学特性，可为低温风洞的结构安全性能优化提供可靠的仿真分析方法。Abstract: In cooling down process, the cryogenic wind tunnel has a wide range of temperature variation, which may lead to strong structural thermal stress and affect equipment smooth and safe operation. The cryogenic wind tunnel diffuser section is investigated in this paper based on fluid-thermal-structural coupling. The data exchange interface for multiple physical fields, MpCCI, is adopted to combine the structural finite element software, Abaqus, and Computational Fluid Dynamics (CFD) software, Fluent. The fluid-thermal-structural coupling model of the diffuser section is established to investigate heat transfer characteristics of the cryogenic internal flow field and calculate the distribution of temperature and stress in the cryogenic wind tunnel structure. The cryogenic wind tunnel experiment indicates that the results of fluid-thermal-structural co-simulation agree well with the test results, which reflect correctly the thermodynamic characteristic of cryogenic wind tunnel structure and provide reliable analysis method for safety performance optimization of wind tunnel structure.
