【摘要】 本文首先对角区湍流场作了详尽的测量,包括平板壁面和翼型表面上的压力分布,角区流场在来流,绕流以及尾流共十个横截面上的平均速度,脉动速度,湍动能和Reynolds应力,然后应用拟压缩性方法,在曲线坐标系下求解N-S方程,选取了B-L湍流模式,对角区湍流场进行数值模拟。最后把计算结果与实验结果进行了对比,二者符合较好。更多还原

【Abstract】 Intensive measurements of various flow parameters in the flow field around the wing-body junction, such as the distribution of the pressure along the airfoil and plate wall, the mean and fluctuation velocity,as well as the turbulence energy, u’v’ and u’w’ etc. ,are performed. A pseudo compressibility approach is used to solve the steady incompressible N-S equation in a curvilinear coordinate system. The numerical results are in good agreement with experimental data.更多还原
