liquid volume fraction造句

• 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。
