流动边界 meaning in English

flow boundary

On three - dimensional numerical solution of incompressible viscous flow by osfem abstract an algorithm for solution of three - dimensional navier - stokes equations for incompressible viscous flow is developed . a decoupled algorithm based on the operator - splitting technique is applied
由于三维粘性流动的复杂性，例如流动边界的选取、控制条件的给定以及混合算子方程高精度数值解法等，都值得探讨和研究。
Horizontal circulation at the inlet of the upper approaching channel of three gorges project can affect the safety of navigation . boundary layers will separate along a curved dike causing horizontal circulation regions which affect the overall flow field and increase sedimentation
类似的由于流动边界出现凸出障碍物引起边界层分离，导致回流发展、流态恶化，造成泥沙淤积等一系列问题的情况，在水利、航道及电站等工程中普遍存在。
