The computation of underwater explosion model with a gas-water interface is discussed where the interface is considered as a special internal boundary. This boundary is represented as doubled-defined points and each point corresponds to one material. The HLLC (Harten, Lax, van Leer, Contact) scheme is implemented in solving ALE (Arbitrary Largrangian-Eulerian Method) formulation on unstructured moving grids to track the material interface. This method is used to compute 1D spherical symmetric underwater explosion model and the solution agrees with the experiment data well. As an expansion, 2D cylindrical underwater explosion model is also computed and a satisfying result is obtained.

在对水下爆炸过程的数值模拟中,把水-气介质界面当作一种特殊的内部边界,并且在该边界上的网格节点都有双重定义,分别对应边界两侧的不同介质状态,通过利用HLLC(Harten,Lax,van Leer,Contact)方法求解任意ALE(Arbitrary Largrangian-Eulerian Method,拉格朗日-欧拉方程)方程组,以及运用界面跟踪和动网格方法,对一维球对称水下爆炸模型进行了数值模拟。结果表明,所得到的数值计算结果与实验结果吻合得较好,并且在扩展到二维柱对称水下爆炸模型时,同样得到了满意的结果。

在对水下爆炸过程的数值模拟中,把水-气介质界面当作一种特殊的内部边界,并且在该边界上的网格节点都有双重定义,分别对应边界两侧的不同介质状态,通过利用HLLC(Harten,Lax,van Leer,Contact)方法求解任意ALE(Arbitrary Largrangian-Eulerian Method,拉格朗日-欧拉方程)方程组,以及运用界面跟踪和动网格方法,对一维球对称水下爆炸模型进行了数值模拟。结果表明,所得到的数值计算结果与实验结果吻合得较好,并且在扩展到二维柱对称水下爆炸模型时,同样得到了满意的结果。

水下爆炸  /  介质界面追踪  /  非结构动网格  /  HLLC方法  /  ALE方程

The computation of underwater explosion model with a gas-water interface is discussed where the interface is considered as a special internal boundary. This boundary is represented as doubled-defined points and each point corresponds to one material. The HLLC (Harten, Lax, van Leer, Contact) scheme is implemented in solving ALE (Arbitrary Largrangian-Eulerian Method) formulation on unstructured moving grids to track the material interface. This method is used to compute 1D spherical symmetric underwater explosion model and the solution agrees with the experiment data well. As an expansion, 2D cylindrical underwater explosion model is also computed and a satisfying result is obtained.
