边界层厚度 [biān jiè céng hòu dù]
[流] boundary layer thickness
- 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。
For water, the ratio of flow boundary layer thickness to film thickness is the minimum under the optimum feeding rate. - 凸起高度不大于0.17倍边界层厚度时，感受性与其成线性关系。
The receptivity increased linearly with the roughness height until it reached a value of 0.17 ( is the thickness of boundary layer). - 根据流动显示的结果，分析了多孔质层、热输运以及边界层厚度减小等支配纳米尺度传热主要因子的影响。
The main factors which dominate the nano-scale heat transfer, nano-particle porous layer, heat transfer and reduction of the boundary layer, are also analyzed with the results of fluid visualization.
