ABSTRAKT

This paper provides an overview of three commonly used methods for solving conjugate heat transfer problems with different solvers for the fluid and solid domains. A fourth new method with improved stability properties is introduced. A novel stability criterion is presented for all coupled methods which allows selecting a suitable method for each application.
The results of the conjugate heat transfer in a flat plate are compared for the four different methods and are validated with analytical solutions. Finally, the conjugate heat transfer is computed in a first stage turbine blade with 5 internal cooling channels. The convergence history between two different methods is compared.
