摘要：

An axial turbine was aerodynamically designed for a ship supercharger, by means of the thermal design of the pulse turbine considering the pulse influence, on the basis of the one of the constant-pressure turbine. Then the design results were compared with the correlative experimental data, and a satisfying conclusion shows the designed axial turbine can meet both the design requirement and the off-design one. Based on this, flow simulation platform was established for the axial turbine on the basis of actual geometrical model by using commercial CID software-NUMECA, especially developed for turbo-machinery, and three-dimensional numerical study was carried out on the inner flow field of the axial turbine. Furthermore, for examining the turbocharger performance under off-design condition, the three-dimensional numerical study and analysis were also done respectively under two conditions with different rotation speed and mass flow with FINE/Turbo, and finally some useful conclusions were drawn.
