为提高熵相容格式的精度,利用限制器机制构造高分辨率格式,将构造的通量限制器插入熵相容格式,得到一类高分辨率熵相容格式.构造Euler方程高分辨率熵相容格式时,对熵相容格式中的几个参数做简单调整,提高了接触间断处的分辨率.将所得格式的数值结果与熵相容格式的数值结果比较表明,构造的高分辨率熵相容格式具有稳健和基本无振荡等特性.
To improve accuracy of entropy consistent schemes,we proposed high resolution entropy consistent schemes by inserting a new flux limiter into entropy consistent schemes. It uses limiter mechanism to construct high resolution schemes. In constructing high resolution entropy consistent schemes of Euler equations,we improve resolution of contact discontinuity by adjusting parameters of corresponding entropy consistent schemes. Several numerical experiments illustrate robustness and essentially non-oscillations of the schemes.
