Abstract�� Numeration analysis was made to simulate the flow and heat transfer in the double-web turbine disk. Several cooling structures of double-web turbine disk with different radial inlet position were proposed based on the same weight as a simplified solid disk. The calculated results present that: structures, in which rotor-stator cavity resorting a center or high positioned cooling air inlet, with the rotating cavity using high positioned inlet both, show better features of heat transfer. The lower volume mean temperature and the lower radial temperature difference are obtained, however, the resistant loss will increase a little.
Keywords�� double-web turbine disc   turbine disk   heat transfer   flow
