| Abstract: | The three dimensional viscous flows in the first stage of NASA67 transonic fan, at near peak efficiency point and near stall point, are investigated numerically employing a commercial software named as FINE/TURBO. Detailed analysis are processed for the computational results with fine mesh employed. The phenomena such as shock/boundary layer interaction, blade tip-clearance leakage vortex, flow separation and radial mixing, are revealed, and the results of secondary flow and energy loss distribution in the flow passages are also can be found in this paper. |
