The Level Set method in body-fitted coordinate for propagation of non-ideal detonation is studied. According to the Hamilton-Jacobi formulation of the Godunov's scheme, we studied finite difference method for the propagation equation of non-ideal detonation in non-orthogonal body-fitted coordinate systems and presented an algorithm. We have shown a few calculations and compared with analytical and other numerical results.

研究在贴体坐标系中采用Level Set方法计算多维非理想爆轰波阵面传播问题,根据Hamiltom-Jacobi方程的Godunov差分格式,提出了非正交的贴体坐标系中Level Set函数方程的差分格式及其相应的数值方法。最后给出了几个典型数值算例,并且与解析结果进行了比较。

非理想爆轰  /  Level Set方法  /  贴体坐标系

The Level Set method in body-fitted coordinate for propagation of non-ideal detonation is studied. According to the Hamilton-Jacobi formulation of the Godunov's scheme, we studied finite difference method for the propagation equation of non-ideal detonation in non-orthogonal body-fitted coordinate systems and presented an algorithm. We have shown a few calculations and compared with analytical and other numerical results.
