This paper presents a variational principle which connects solid and fluid temperature fields in the analysis of thermally coupled problems. The principle satisfies the equilibrium condition of heat flux on the boundary. The combination of this principle and a hybrid type virtual work principle for flow problems is applicable to the analysis of the thermally coupled problems between solids and fluids. This paper also formulates a finite element method (FEM) based on the combined principle. The FEM eliminates an iterative calculation to satisfy the equilibrium condition on the boundary. The FEM is applied to a heating problem for a vertical plate with a heat source. The use of the FEM gives good accurate results in comparison with experimental ones.
