Numerical Calculation of Three-dimensional Laminar Boundary Layer on a Body of Ellipsoid at Incidence
【摘要】 利用驻点方程和周向相似确定头部边值分布,提出一种宜于工程应用的头部简化处理方法,计算了椭球体有攻角绕流的三维层流边界层流场及三维边界层纵向分离和周向回流.计算结果与实验结果吻合良好.
【Abstract】 A simple method of head body simplied for engineering use is given.By using stagnation equations and circumferential similarity initial velocity profiles of head body are found out.The flow field of three-dimensional boundary layers on body of ellipsoid at incidence and meridional separated and circumferential reverse flow have been calculated.The calculation results agree with experimental data.
