Abstract
To achieve rapid and accurate analysis of propeller slipstream effects on high-lift configurations,this study employed both the full blades method(FBM)and actuator disk method(ADM)for numerical simulations under advance ratios J=0.7,1.0 and angles of attack ranging from-4°to 24°.The results showed that although there were local differences in time-averaged actuator disk load distributions between isolated propellers and propellers integrated with high-lift configurations,the pressure distributions and lift/drag results obtained by applying these different load sources in ADM calculations were fundamentally consistent.The differences in overall lift coefficient did not exceed 4.3%,and drag coefficient deviations remain below 5.4%,demonstrating that using actuator disk loads from isolated propellers had minimal impact on full-aircraft aerodynamic calculations,thereby avoiding complex grid generation.By converting unsteady computations to steady-state solutions while maintaining equivalent grid resolution(33 million cells),ADM achieved results that closely match FBM before stall(α＜20°),with computational time reduced to approximately 1/18 of FBM(170 vs.3100 core-hours).The ADM method thus provides an efficient and reasonable approach for evaluating propeller slipstream effects on high-lift devices.关键词
