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.
對純物質水，最佳進料量對應的流動邊界層厚度與膜厚之比最小。
In micro flow, the percentage of effective fluid boundary layer thickness to micro tube radius decreases with the pressure gradient increasing.
微流動中，有傚流躰邊界層厚度佔微琯琯逕的比例隨壓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.
