Abstract:
After using in [R2] the adaptive mesh finite volume method according to Huazhong TANG and Tao TANG in [R3], and Arthur Van Dam in [R1] to solve three test problems, we noticed that the numerical solutions are not sufficiently accurate. Those three problems are the following: a Burger’s problem with a diffusion term, a problem of two waves traveling in opposite directions with a source term and the SOD’s Shock Tube Problem with a diffusion term. The purpose in this paper is to improve the accuracy of the numerical solutions by using a high-order scheme in the finite volume method.
