Design and development of dynamic parallel computing code for three-dimensional gaseous detonation
摘要
Abstract
In numerical simulation of three-dimensional gaseous detonation,a large number of grids resul- ting 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. Com pared 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.关键词
