Compared with the original elm , the numerical experiments show that the improved elm has lower numerical dissipation , higher accuracy , and better performance over steep topography
数值试验表明，改进后的欧拉拉格朗日方法在水深变化剧烈处比改进前的数值耗散更小、精度更高和表现更合理。
To ensure the numerical dissipation much smaller than the physical viscous terms , directional scaling of the artificial dissipation is achieved and proper boundary conditions are also introduced in this term
为保证高雷诺数下n - s方程的数值粘性远小于物理粘性,对人工粘性项进行了方向性修正并引入适当的边界条件。
However , when we use these schemes to compute the initial problem of hyperbolic conservation laws , there is still numerical dissipation near the interface , that is to say , the resolution is decreased near the interface
但是，我们知道，即使用这两种格式来计算双曲守恒律方程的初值问题，在间断面的附近仍会发生数值耗散，也就是说在间断处的分辨率降低了。
For scalar equation and system of equations , we build different ghost fields , translate one equation ( system ) into two equations ( system ) . we still use high resolution shock capturing method to compute the two equations ( system ) ; level set equation is used to track the interface , and the result of original equation ( system ) is determined by the level set function . thus , we eliminate the numerical dissipation which high resolution shock capturing method cannot avoid near the interface , and the resolution is enhanced
对标量守恒律方程、守恒律方程组分别构造了一种虚拟区域，将一个方程(组)转化成两个方程(组) ，对这两个方程(组) ，我们仍然使用高分辨率激波捕捉格式，而levelset方程用来追踪间断的位置，原方程(组)的解最后由levelset函数决定：这样做弥补了高分辨率激波捕捉方法在间断附近发生数值耗散的缺陷，提高间断处的分辨率。
The investigation in this dissertation shows the capabilities of ausm + scheme , such as the exact resolution of shock , low numerical dissipation , simple and requiring less computational effort . the successful applications on supercritical airfoils and wings show that the present flow solvers based on ausm + scheme are of valuable and promising in practical application
