摘要
介绍了动网格的更新方法,并且结合湍流模型、汽化模型在fluent平台上对内弹道进行仿真。仿真结果表明,导弹出筒速度与实际试验结果吻合程度相当好,误差在1%以内,仿真方法对实际工程有重要的指导意义。
The method of updating dynamic grid is mainly introduced, and integrated with turbulent model and boiling model to simulate interior trajectory in fluent software. The result of simulation indicates that the velocity accords with the result of experimentation, and the error is less than one percent, the simulation method is very importantly directive to the practical engineering.
