Abstract

In order to study the thermal coupling properties of aerated oil medium steel-basalt mineral composite (BMC) joint surface and establish an accurate and convenient simulation analysis method. The calculation method of the actual contact area ratio weight matrix of the aerated oil medium steel-BMC joint surface was studied. The virtual material theory model of the thermal coupling performance of the aerated oil medium steel-BMC joint surface was established by combining it with the virtual material theory. Based on the virtual material method, the thermodynamic coupling performance of the aerated oil medium steel-BMC joint surface was studied by finite element simulation, and compared with the experiment and numerical simulation methods of fractal theory. The results show that the temperature and strain changes of BMC specimen with virtual material method have a good coincidence with the experimental results, and the relative error is minimal. At the same time, the virtual material simulation model is simple, less computation and higher efficiency. It is proved that the method in this paper has better precision and convenience.

加气油介质钢- bmc接合面热力学耦合性能分析与模拟

为了研究加气油介质钢-玄武岩矿物复合材料（BMC）节理面的热耦合特性，建立一种准确、方便的模拟分析方法。研究了加气油介质钢- bmc结合面实际接触面积比权重矩阵的计算方法。将其与虚拟材料理论相结合，建立了曝气油介质钢- bmc接合面热耦合性能的虚拟材料理论模型。基于虚拟材料方法，对加气油介质钢- bmc结合面的热力学耦合性能进行了有限元模拟研究，并与分形理论的实验和数值模拟方法进行了比较。结果表明，虚拟材料法测得的BMC试样的温度和应变变化与实验结果吻合较好，且相对误差最小。同时，虚拟材料仿真模型简单，计算量少，效率高。实践证明，该方法具有较好的精度和方便性。

期刊介绍： Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
