normal neutral plane
解釋
幾何中性面-
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
在風洞中對水平光滑平板以及加有粗糙元平板的邊界層轉捩進行了測量與研究,比較了不同情況下平板邊界層內由振動梁激勵生成的t - s波沿流向和法向強度的分佈規律,得到了相應的振型增長曲線以及中性曲線。
