摘　　要：通过构造一个分布函数 ,利用无碰撞的Boltzmann方程 ,推导出求解一般形式的KFVS方法 ,对一维溃坝进行了模拟 ,并与精确解进行了比较 ,说明了这种方法的进步性和可行性 .Through a construction of a distribution function,the normal form of KFVS is deduced based on the nocollision Boltzmann equation.A dam breaking flow is simulated and the result are compared with those from exact solutions.The agreements are satisfactory.It is shown that the model offered in this article has some progress and it is feasible.
