| Abstract: | Regarding burning surface as moving interface,we use Level Set interface chasing method to capture the changing process of the burning surface and calculate its area in real time.Fifth-ordered Weighted-ENO and Third-ordered TVD Runge-Kutta schemes are employed respectively in space and time dispersion.Based on parallel burning algorithm,a certain star like grain is used as test case for both Level Set and Solid Modeling method,and the comparison shows that their results are almost equivalent.Moreover,a one-... |
