Examples
- 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。 - Under the circumstances that the ball rubs the pot to revolve round the sun on the function with high - speed rotation , ball rub to grind ball form to supplies heavy high frequency strike , grit strength very under function of mass force pot , grind or mix fast the supplies

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。 - Firstly , based on the present research all over the world , a 3d quasi - single phase model is built together with k - equations . the special feature of this model is taking account of the influence of interaction between liquid and gas , that is to say , the influence of interphase drag force , lifting force perpendicular to the relative velocity , virtual mass force and gas or liquid volume fraction in the fluid field have been considered . a 3d two - fluid model is also built in order to describe more accurately the fluid flow on distillation trays by comparing the computational results of quasi - single phase mathematical model with of two - fluid mathematical model
本文在国内外已有的研究基础上，首先建立了以k - (封闭模型为基础的三维拟单相流模型，该模型的特点在于充分考虑了气液两相间相互作用的影响，即计入了相间曳力、横向升力、虚拟质量力和气、液相含率对流场的影响；并建立了塔板三维双流体模型，主要目的是通过对比拟单相流数学模型、双流体数学模型的计算结果，建立能够准确描述塔板上流体流动的数学模型。
