For a time, surface and subsurface current are in opposite directions; flow is seaward at the surface and landward near the bottom.
在一个时期，表层和次表层的水流方向相反；表层水流向外海方向流动，靠近底层的水流则向陆地方向流动。

The flow field parameter distribution can be affected more in upper stream, especially near the leading edge area while the Mach number distribution of the upstream blade surface is affected little.
对上游进口段，特别是靠近叶片前缘区域流场参数分布有较大影响，但对于上游叶片表面马赫数影响不大。

It has been found that at the jet flow cross-section near the impingement surface accompanied by the appearance of two counter-rotating vortex pairs there emerge two eccentric peak values.
