boundary layer thickness

基本解释

For water, the ratio of flow boundary layer thickness to film thickness is the minimum under the optimum feeding rate.
对纯物质水，最佳进料量对应的流动边界层厚度与膜厚之比最小。
In micro flow, the percentage of effective fluid boundary layer thickness to micro tube radius decreases with the pressure gradient increasing.
微流动中，有效流体边界层厚度占微管管径的比例随压力梯度的增大而降低；
The analysis result of velocity distribution and boundary layer thickness is put forward in the boundary layer and cored region for laminar and turbulent flow of pipeline.
采用动量积分方法推出了管道流动中的速度边界层方程，给出了管道层流和紊流时速度边界层和核心区中的速度分布、边界层厚度的解析结果，并与冯。
