| Abstract: | The arbitrary Lagrangian-Eulerian equations are applied to study the numerical simulation of the chemical non-equilibrium muzzle flow fields with movable pill.The convection term is solved with HLLC method and the chemical reaction is dealt with an elementary reaction model.By using unstructured dynamic grid based on local remeshing method,the variation of grid caused by projectile movement was analyzed.A parallel arithmetic based on dynamic unstructured grid and multiply-connected domain for the jet combus... |
