摘要
本文针对含有表面张力为源项的不可压Navier-Stokes方程,在非交错网格下比较研究了两类处理源项的Projection方法。并比较研究了网格中心点处,压力梯度和表面张力的两种不同计算技术。表面张力通过CSF(ContinuousSurface Force)模型来计算。文中对一初始处于静止状态无外力作用的液滴进行模拟,通过分析虚假流速和压力分布来讨论各方法的优缺点。
A comparison between two algorithms is conducted with a collocated mesh for incompressible Navier-Stokes equations with the surface tension as a source term. Two different techniques are employed for calculation of the pressure gradient and the continuous surface tension. For an initial static bubble without gravity, the spurious currents and pressure distribution are shown to illustrate the differences between the algorithms for treatment of the source term and between the techniques for calculation of the pressure gradient and the surface tension.
