Abstract
A coupled heat transfer (CHT) solver was established. The solver couples the N-S equations with the heat conduction equation using the finite volume method. The developed CHT solver was verified by Mark II 5411 case. The numerical results agree well with experimental data, proving the accuracy of the developed CHT code. The solver was applied to the coupled heat transfer simulations of an air-cooled turbine with a single cooling channel. Adiabatic results and CHT results were compared. Different turbulence and transition models were employed. The result shows that the developed code is of great use in engineering simulations, and in order to predict thermal loads on turbine vane accurately, transition needs to be considered.
