quasi-viscous flow

When the motion of the basic state is the shear flow ( or the differential rotation), this property means that the unstable waves would evolve automatically into the quasi-stationary stage.

当基态运动为剪切流（或较差旋转）时，这一性质将使不稳定波自动演化到准稳阶段。

The air flow was regarded as quasi-laminar.

空气流动被视为准层流.

A Study of the Quasi Three-dimensional Design Method for an Advanced Steam Turbine and an Analysis of Its Flow Patterns

先进汽轮机准三维设计方法研究与流型分析

The results show: ( 1) the distribution of swirling flow field in the said square-shaped separator has a forced swirl in the centre, but a quasi-free swirl near the side wall, and a partial swirl existing in the place of edge-angle.

结果表明：（1）方形分离器内的旋流流场呈中心为强制涡而边壁附近为准自由涡分布，在边角位置存在局部旋涡。

In addition, we also computed the quasi three dimensional flow field in turbine machine.

另外，还用本方法的思想计算了叶轮机内部准三元流动。
