A Conjugate Heat Transfer (CHT) analysis allows the calculation of the heat transfer and temperature of a body placed in a fluid. The CHT analysis takes into account both the conduction in the solid and the convection in the fluid. Present paper describes a CHT method that uses two separate solvers: one CFD solver dedicated to the flow calculation and one Finite Element Analysis (FEA) solver for the computation of the heat transfer in the solid. Several methods, combining both codes in order to solve the CHT problem, are explained andevaluated. The CHT method is tested on two turbomachine applications.
