| Abstract: |
| In numerical simulation of three-dimensional gaseous detonation,a large number of grids resulting from relative mesh resolution and large-scale computing domain consume tremendous computing resources,which brings a great challenge for the numerical simulation.Based on MPI parallel mode,this paper uses 5-th order WENO scheme to discrete partial differential term of the governing equations with chemical reaction,and develops high-resolution dynamic parallel code.Then it is used to simulate the propagation of detonation in square tube with obstacle.The numerical results show that high-resolution dynamic parallel code can effectively simulate the propagation of 3-D gas detonation in large-scale tube.It not only improves the computational efficiency but also the resolution of the detonation wave front.Compared with static parallel mode,high-resolution dynamic parallel code saves communication time of data in interface,and further enhances the computational efficiency.So,it is an effectively means to explore new physical mechanism of 3-D gaseous detonation. |
