Simulation of jet flow during missile launching with dynamic mesh

The thesis take an efficient way, dynamic mesh technology integrating partial unstructured grids with spring-based smoothing method and remeshing method, to calculate unsteady flow between missile and launch canister which include relative movement. It takes missile laid in the launch canister as movement entity, with the missile moving, the boundary of the corresponding flow field will change. We can make a conclusion from the result: it has high precision using dynamic mesh to simulate unsteady flow of jet flow in the process of missile launch.
