拖曳角 的英文怎麼說
中文拼音 [tuōyèjiǎo]
拖曳角
英文
drag angle-
The mechanism of the downburst formation was also investigated based on the cloud microphysics of the simulated storm and it was found that this downburst was primarily produced by hail loading, and enhanced by hail melting and rain evaporation. and the loading and the melting of hail played a very important role in producing the downburst. the gale at the surface was caused by the severe downburst
從雲微物理學角度分析了此次局地性大風的形成原因，認為由高空冰雹粒子的拖曳產生的負浮力作用是促發強下沉氣流產生的主要原因，其次是冰雹的融化和雨水蒸發冷卻對下沉氣流起加速作用，冰雹的拖曳和融化作用對下沉氣流具有決定性的作用。Sets up three - dimensional movement modal of towed - cable, the vector dynamic equilibrium equation is expanded under local coordinate, and numerically discreted by central difference on time and space through transforming eular angle
摘要建立拖纜的三維運動模型，通過歐拉角的變換把拖曳線列陣微元段矢量動力平衡方程在局部坐標系下展開，在時間和空間上作中心差分數值離散。The vortex - vibration was measured when the towed velocity, dip angle between the circular cylider and flow velocity, and diameter were varied
對不同拖曳速度、拖纜傾角，即拖纜與來流速度之間的夾角和不同直徑的拖纜渦激振動進行了測量分析。Experimental data from the towing tank tests show that the hydrofoils give more water - drags on the raft ' s hull, and that the hydrodynamic performance of a ferrying raft will be improved by rational designs of the hydrofoils ' profile, angles of attack as well as the position of hydrofoil on the hull
船模水池中的模型拖曳試驗表明，盡管水翼會增加門橋的水阻力，但只要合理地設計水翼的翼型、攻角和安裝位置，可以改善和提高門橋水動力性能。Being the nonlinear function of attack angle, the hydrodynamic forces acting upon the submersible are determined by a towing tank test
作用於潛水器上的水動力系攻角的非線性函數，可用拖曳水池試驗加以測定。Result shows that the dip angle, the towed velocity and reduced velocity are main influence factors to the vortex - induced vibration of a circular cylinder
結果表明，約化速度、拖纜傾角、拖曳速度等是影響渦激振動的主要因素。分享友人
