virtual mass meaning in English
实效重心
虚质量
有效质量视质量
Examples
- Principle of minimum virtual mass
最小虚质量原理 - The forces acted on the bubbles are drag , virtual mass , lift , wall lift , pressure gradient , and gravity
气泡受力包括相间阻力、虚质量力、升力、壁面升力、压力梯度和重力等。 - The ipsa model solves the navier - stokes equations of each phase with the interphase interactions between two phases of water and air , including the interphase drag forces , interphase lift forces , interphase pressure and virtual mass forces
Ipsa模型对每一相求解n - s方程，并考虑水-气体两相间的相间相互作用，包括相间阻力、相间升力、相间压力和虚质量力。 - In the 1 ight of results , the interphase pressure can be ignored and the interphase lift force plays a trifling role in the friction reduction , while the gravity - buoyancy , the interphase drag force and the virtual mass force are influential , especially in the bigger bubble
结果表明，相间压力可以忽略掉，相间升力起的作用比较小，而重力-浮力、相间阻力和虚质量力的影响比较大，特别是在大气泡中。 - The model of fpsa ( inter - phase slip algorithm ) provided in phofvmcs , the software used in computational fluid dynamics , which solves the navier - stokes equations of each phase with the interphase interactions between two phase of water and air , including the interphase drag forces , interphase lift forces , interphase pressure and virtual mass forces , is employed with the difference scheme of upwind and the orthonormal grid
计算采用由phoenics (计算流体力学软件)的ipsa (相间滑移算法)模型，应用upwind (迎风)格式和直角坐标网格。 ipsa模型对每一相求解n - s方程，并考虑水-气体两相间的相间互互作用，包括相间阻力、相间升力、相间压力和虚质量力。
