Two - order enhanced un - split finite volume euler method for multi - fluid flow , which combines the roe approximate riemann solver , is developed to simulate the multi - fluid interactions , such as the fluid described by polynomial eos , stiffen gas eos , jones - wilkins - lee ( jwl ) gaseous explosive eos , cochran - chan ( cc ) solid explosive eos and hom shock wave eos , etc . numerical results of the id , 2d and 3d multi - fluid interaction examples show that the high - resolution method and interface capturing equations can resolve the multi - fluid flow correctly and successfully . a simple fluid - mixture type ppm algorithm for multi - fluid flow , which is based on vof interface capturing method and resolved by langange / remap two steps , is developed to simulate the high density or high pressure ratio flow at both sides of the interface 本文提出了實(shí)用于多介質(zhì)流體的增強(qiáng)型二階精度有限體積歐拉數(shù)值計(jì)算方法,采用roe方法近似求解riemann問題,可以適用于多項(xiàng)式狀態(tài)方程、 “ stiffengas ”狀態(tài)方程、 jones - wilkins - lee爆轟產(chǎn)物狀態(tài)方程、 cochran - chan固體炸藥狀態(tài)方程以及hom狀態(tài)方程等,并對(duì)多介質(zhì)流體相互作用的一維、二維、三維問題進(jìn)行數(shù)值計(jì)算,數(shù)值驗(yàn)證了本文給出的高精度差分格式和界面捕捉方法的正確性,兩種方法耦合形成的多介質(zhì)流體數(shù)值計(jì)算方法是成功的。
South high temperature and wet climate easily leads asphalt pavement to water damage , this writer participated in the guangdong meihe highway asphalt pavement construction , mainly through the asphalt mixture marshall immersion test , splitting freeze - thaw test anylyze asphalt mixture types and asphalt content ' s influences to the water stability , and gives the linear fitting relationship about the soaking remnants stability and freeze - thaw splitting strength and oil - stone ratio . and water stable indicators and the oil - stone ratio ' s second linear fitting relationship , finally stressed asphalt and asphalt amount significance to water stability 摘要通過瀝青混合料的浸水馬歇爾試驗(yàn)、凍融劈裂試驗(yàn)分析了瀝青類型及瀝青用量對(duì)瀝青混合料水穩(wěn)定性的影響,并給出了浸水殘留穩(wěn)定度與凍融劈裂強(qiáng)度與油石比的線性擬合函數(shù)關(guān)系,以及水穩(wěn)性指標(biāo)與油石比的二次函數(shù)關(guān)系,最后指出改性瀝青和瀝青用量對(duì)混合料水穩(wěn)定性的意義。
