| Abstract: | Based on the theory of molecular dynamics the authors have studied and developed a class of new type upwind schemes kinetic flux vector splitting (KFVS) schemes, whose L stability and upwinding are proved. Then, the construction of high accurate schemes are given. Finally, the present schemes are tested on 1 D shock tube problem, and the numerical results are compared with the exact solutions, and are satisfied. |
