For Riemann problem in n(n ≥ 3) dimensional(n-D) conservation laws, dimension of equations can be only reduced one dimension by applying self-similar approach, so transformed equations are at least two dimensional (2D) equations which are also very hard although some pioneer works have been done in references [1-3]. 展开更多
