Numerical schemes with high order of accuracy for the computation of shock waves

High order accurate scheme is highly desirable for flow computation with shocks. After analysis has been made for the reason of the generation of non_physical oscillations around the shock in numerical computations, a third_order, upwind biased, shock capturing scheme was proposed. Also, a new shock fitting method, called pseudo shock fitting method, was suggested, which in principle can be with any order of accuracy. Test cases for one dimensional flows show that the new method is very satisfactory.
