光滑平板 meaning in English
smooth flat plate
Examples
- Comparing with the neutral cave on the smooth plane that was thumb - like and opened at the bottom , the neutral caves on the plane with single roughness elements were closed circles . with the growing of roughness element s height , the closed circle became smaller
实验中发现与光滑平板边界层的下端开放式的拇指型中性曲线相比较，有粗糙元平板的中性曲线为封闭式的环形曲线，随着粗糙元高度的进一步增加中性曲线收缩为更小的闭合环。 - It is validated that the numerical methods can absolutely predict the flow in the microchannels . the flow field around the roughness and the pressure drop of midline along flow direction are analyzed . it ' s found that the range of the pressure drop change relate to the magnitude of relative roughness , the distance between two parallel planes , the re number and ratio of the size of roughness and the distance between two roughness
通过对粗糙元周围流场和充分发展段中心线压力曲线的分析，发现有粗糙元存在的两平行平板间微通道，其充分发展段压降大于光滑平板充分发展段压降；当相对粗糙度和re不变时，随着板间距的减小，粗糙度对主流的影响不断增大；当板间距和相对粗糙度不变时，在层流状态下，粗糙度对流动的影响不随re的变化而变化；当板间距和re保持不变时，相对粗糙度越大，其对流动的影响就越大。 - An experimental investigation on the transition in the boundary layer of horizontal plane with and without single two - dimensional roughness elements has been carried out in the wind tunnel . the distribution in normal and stream - wise directions of intensity of t - s wave excited by vibrating beam was measured in every condition . neutral curves were obtained by measuring the growth of the t - s wave at the normal critical location along the stream - wise direction
在风洞中对水平光滑平板以及加有粗糙元平板的边界层转捩进行了测量与研究，比较了不同情况下平板边界层内由振动梁激励生成的t - s波沿流向和法向强度的分布规律，得到了相应的振型增长曲线以及中性曲线。
