摘要
本文进行了等温可压缩两相流的VOF数值模拟的研究。我们首次对等温非可侵入可压缩两相流的数学模型进行直接推导,得到用统一的压力、密度描述的方程组。可压缩状况下指示函数方程与不可压缩两相流不同,存在源项,推导出的源项的表达与其它文献使用渐近分析得到的形式等价。本文使用实验数据验证了VOF界面捕捉模型,并对液-液可压缩流进行的数值试验。
A numerical simulation study of isothermal compressible two phase flow with the Volume of Fluid（VOF） was provided.First,the mathematic model for isothermal compressible two phase flow in a direct mode with uniform pressure and density was deduced and the equation of indicator function is different from incompressible two phase flow because of the source term which is equivalent to the form deduced with asymptotic analysis by others.The validation of VOF interface capture was conducted with experiment data and the numerical experiment for liquid-liquid compressible flow was presented.
