Our reseach team will develope the variational principles for temperature of solid and fluid. Both principles have the equilibrium condition of heat flux on the solid and fluid boundarys. The combination of both principles and a hybrid type virtual work principle for flow problems is applicable to the analysis of the thermally coupled problems between solid and fluid.We also formulate the finite element method (FEM) based on the above principles in order to analyze the superheating and/or overcooling behaviors for semiconductors. Moreover, the FEM can be used to prevent their broken-down conditions due to thermal straining when they are superheated and/or overcooled.

我们的研究小组将发展固体和流体温度的变分原理。这两种原理都具有固体和流体边界上的热流密度平衡条件。两种原理的结合以及流动问题的混合型虚功原理适用于固流热耦合问题的分析。在此基础上，建立了分析半导体过热和过冷行为的有限元方法。此外，FEM可用于防止它们在过热和/或过冷时因热应变而破裂的情况。
