This thesis presents the high resolution numerical simulation methods for multi - fluid dynamics . the main contents include three parts : the first is a set of interface capturing equations deduced to describe the interface evolution , which is suitable for constructing two - order enhanced un - split finite volume scheme and three - order parabolic - piecewise - method ( ppm ) scheme in euler coordinate ; the second is the capabilities of level - set method for tracking multi - fluid interfaces are unproved ; the third is that the computational resolutions are much more advanced by improving adaptive mesh refinement ( amr ) technique 主要研究目的是獲得多介質(zhì)流體流動的高精度數(shù)值模擬方法,主要內(nèi)容包括界面捕捉方程的推導(dǎo),適用于euler坐標(biāo)系的增強型二階精度非維數(shù)分裂有限體積計算格式和三階精度ppm格式構(gòu)造,以及發(fā)展改進(jìn)levelset方法提高捕捉流體界面的能力,發(fā)展改進(jìn)網(wǎng)格自適應(yīng)技術(shù)提高各類方程解的計算精度。
