abstract

The effect of mixing plane boundary condition in conjugate heat transfer analysis is studied. The vehicle is a 1.5 stage warm turbine rig solved using a loosely coupled fluid/solid heat transfer method. To reduce the elapsed time, two and three dimensional CFD cavities are solved simultaneously in a Graphics Processing Units (GPU) cluster. The experimental data are compared against a coupled model with mixing plane distributions obtained from an adiabatic case. A moderate influence of the mixing plane on the results is observed, with non-dimensional temperature differences around 2% in some locations.
