quasi-two-dimensional flow

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。

The angular motion of the models during the quasi-steady flow was recorded by synchroflash and the aerodynamic stability coefficients were derived from the motions by parameter differential method.

采用同步高速摄影方法记录了20ms准定常试验时间中模型的角运动并用参数微分法进行气动参数辨识。

应用准三元流动分析的涡轮性能预测研究

The air flow was regarded as quasi-laminar.

空气流动被视为准层流.

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。
