混合类型
Examples
- 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
本文提出了实用于多介质流体的增强型二阶精度有限体积欧拉数值计算方法，采用roe方法近似求解riemann问题，可以适用于多项式状态方程、 “ stiffengas ”状态方程、 jones - wilkins - lee爆轰产物状态方程、 cochran - chan固体炸药状态方程以及hom状态方程等，并对多介质流体相互作用的一维、二维、三维问题进行数值计算，数值验证了本文给出的高精度差分格式和界面捕捉方法的正确性，两种方法耦合形成的多介质流体数值计算方法是成功的。 - 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
摘要通过沥青混合料的浸水马歇尔试验、冻融劈裂试验分析了沥青类型及沥青用量对沥青混合料水稳定性的影响，并给出了浸水残留稳定度与冻融劈裂强度与油石比的线性拟合函数关系，以及水稳性指标与油石比的二次函数关系，最后指出改性沥青和沥青用量对混合料水稳定性的意义。
