讨论了高分辨率动力学通量矢量分裂有限体积法的推广。在该方法中，提出了对麦克斯韦公式的适当修正，通过附加保守方程来恢复欧拉方程。基于已知的欧拉方程与玻尔兹曼方程之间的联系，提出了一类求解多组分流动欧拉方程的高分辨率KFVS有限体积法。该方法不需要求解任何黎曼问题和压力满足的附加非保守方程，也不需要添加任何非保守修正。数值解在材料前缘附近无振荡，并产生正确的激波速度。［
It concerns the extension of high resolution kinetic flux\|vector splitting (KFVS) finite volume methods.In this new method,a suitable modification of Maxwellian is proposed to recover the Euler equations with an additional conservative equation.Based on the well\|known connection between Euler equations and Boltzmann equations,a class of high resolution KFVS finite volume methods are presented to solve Euler equations governing multicomponent flows. This method does not solve any Riemann problems and additional nonconservative equation satisfied by pressure,and needs not to add any nonconservative corrections.The numerical solutions are oscillation\|free near material fronts,and produce correct shock speeds.
