摘要

摘要:
为探究下表面射流关键参数对超临界翼型气动性能的影响，采用雷诺平均Navier-Stokes （RANS）方程与Spalart-Allmaras （S-A）湍流模型进行数值模拟。通过比较基准RAE2822翼型与下表面射流翼型的流场，验证下表面射流能够在翼型后缘诱导产生逆时针分离涡，带动流线向下偏折，增加了翼型的等效弯度，同时加大前缘的吸力峰，从而提高翼型的气动性能。进一步探究射流位置、射流动量系数、射流角度、马赫数等关键参数对RAE2822翼型气动性能的影响规律。结果表明：给定状态下，下表面射流的位置越靠后，动量系数越大，翼型的气动性能越优。下表面射流在α=0°和2°时的最优射流角度为110°，在α=4°时的最优射流角度为160°，且在最优射流角度下能有效提高翼型马赫数在0.3~0.6范围内的气动性能。

Abstract:
To investigate the influence of key parameters of the lower surface jet on aerodynamic performance of supercritical airfoil, a numerical simulation is performed using Reynolds average Navier-Stokes (RANS) equation and Spalart-Allmaras (S-A) turbulence model. By comparing the flow field between the benchmark RAE2822 airfoil and the lower surface jet airfoil, the lower surface jet induces a counterclockwise separation vortex at the trailing edge of the airfoil, deflecting the streamlines downward. This deflection increases the equivalent camber of the airfoil and the suction peak of the leading edge, leading to the aerodynamic performance enhancement of the airfoil. The effects of key parameters such as the jet position, the jet momentum coefficient, the jet angle and the Mach number on the aerodynamic performance of RAE2822 airfoil are explored. The results show that under given conditions, the closer the lower surface jet is to the trailing edge and the greater the momentum coefficient is, the better the aerodynamic performance of the airfoil. The optimal angle of the lower surface jet is 110° at α=0° and 2°, and 160° at α=4°. The aerodynamic performance of the airfoil can be effectively improved at the optimal angles with the Mach number varied from 0.3 to 0.6.
