A three dimensional incompressiblegas-liquid two-phase flow model was proposed to accurately simulate the fluid flow of casting's mould filling process.
为了更精确地模拟铸造充型过程的流动行为，建立了充型过程的三维不可压缩气。液两相流动模型。

It is shown that so long as the restrained gas exists, there are two P waves and one S wave, even though the fluid phase is incompressible.
结果表明，甚至当液相为不可压缩时，由于束缚空气的存在，饱水土体中亦存在着两种P波。

In the process of investigation, it is assumed that gas flow through the exhaust diffusers is of one dimensional quasi-steady incompressible flow.
