| Abstract: |
| Wave-speed is very important for HLLC method.If the wave-speed is too small,the wave characters can not be catched;if it is too large,there would be more viscosity in the calculation.There are a lot of methods be caught to determine the wave-speed,but every method has its applicability.This paper presents a modified HLLC method without estimating wave-speed,and it is applied to simulate the Baer-Nunziato model.It is compared with three classic wave-speed estimating methods.Numerical results show that the new method is better than others. |
