CALCULATION OF COMPRESSIBLE FLOW AND HEAT TRANSFER ON A ROTATING DISK

In this paper, "BOX" method is extended to swirling compressible flow on a body of revolution, after the boundary layer equation is non-dimensionalized. The torque coefficients and local heat transfer coefficients in the laminar, turbulent and transitional flow regions on the rotating disk are calculated. The variable air properties are taken into account in the calculation. The investigation shows that the modified two-layer turbulence model is suitable to the calculation of the flow on the rotating disk. An appropriate analytical formulation of the turbulence model and relevant constants are also given.
