A NOVEL METHOD FOR THE COMPUTATION OF CONJUGATE HEAT TRANSFER WITH COUPLED SOLVERS
Краткое описание
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.
