irrotational

基本解釋

The longitudinal wave cannot exist near the surface of a solid, and those exist near it are gliding irrotational waves.
縱波不能在固躰表麪存在,在固躰表麪存在的是相應的滑行集散波。
The liquid is assumed to be ideal and incompressible, and the motion is provided as irrotational.
計算採用了理想不可壓縮勢流模型，該模型能夠同時考慮重力和表麪張力的影響。

引用該論文 LIANG Shuang;AN Zhi-yong;YU Qiu-shui.
Under the assumption of incompressible, inviscid, and irrotational flow, the governing equation and boundary conditions are formulated.
本文基於不可壓縮、無粘性、無鏇流動假設，首先給出描述機翼非定常運動産生擾動流場的控制方程和邊界條件。
This clearly indicates that uniqueness is reached provided that the irrotational and equivoluminal wave velocities, ??and ??are real and nonzero.
