本文用隐式近似因子部分通量分裂算法计算了跨音速流中攻角范围达19 °的半球-圆柱体粘性分离绕流。研究了所得到的流场结构，包括物体背风侧的旋涡流和三维分离模式。计算结果与实验数据定性和定量吻合较好。此外，可视化的流场模式已经产生了洞察的三维分离流的行为。
Viscous separated flow surrounding a hemisphere-cylinder body at angles of attack ranging up to 19 deg in transonic flow has been computed using an implicit, approximately-factored, partially flux-split algorithm. The resulting flowfield structures, including the vortical flow on the leeward side of the body and the three-dimensional separation patterns, have been investigated. The computed results show good qualitative and quantitative agreement with experimental data. Furthermore, visualization of the flowfield patterns has yielded insight into the behavior of the three-dimensional separated flow.
