| Abstract: |
| In this paper,the original two-dimensional space-time conservation element and solution element(CE/SE) method is improved by proposing a new design of conservation elements and solution elements.First-and second-order improved CE/SE schemes are deduced and the derivation method of high-order improved CE/SE schemes is given.The numerical test problems such as shock wave reflection,down a step and pass a tube with clapboard are simulated by the improved CE/SE schemes.The numerical results show that the improvement on CE/SE method is successful.The improved CE/SE method has many advantages and deserves extension in numerical simulations. |
