摘要: 采用守恒型的跨音速全位势方程计算了机翼的气动性能,包括表面压力分布,力和力矩系数。计算中未计及粘性效应。坐标变换采用Joukowsky变挟。计算采用Jameson超松弛逐次线迭代格式(SLOR)和逐次加密网格技术。以ONERA M6机翼作为算例。计算结果表明与其他采用全位势方程的计算结果以及实验结果符合很好。

Abstract: A finite-difference relaxation method is used for numerical solution of consevative type 3-Dsteady full potential equation. Computations give the results for wing performance included surface pressure distribution, force and moment coefficients. In the computation, Joukowsky tranform,successive line over-relaxation (SLOR) scheme of Jameson and multigrid technique are used. Test runs for ONERA M6 wing coinside with satisfaction to other computational results and experimental data.
