| 中文摘要: |
| 研究三维多介质界面处理及数值模拟问题。采用拉格朗日法、欧拉法相结合的方法在矩形网格上离散差分基本方程组；在欧拉步中引入模糊方法处理界面，计算各输运量；编写了数值模拟程序，并对线型装药金属罩聚能射流模型进行模拟。证明模糊界面描述和模糊输运计算有效、可行。 |
| 英文摘要: |
| The problem for three-dimensional interface treatment and numerical simulation was studied. Control equations were discrete in rectangle cells because coupling Lagrangian method and Eulerian method was adopted. A fuzzy technique was introduced to treat interface and to calculate transport quantity on Eulerian step. The numerical code is applied to simulate line-shaped charge jet with metal cover. It proves fuzzy interface description and fuzzy transport calculation are effective. |
