摘要: |
采用计算燃烧学方法对火箭发动机非线性燃烧不稳定工作过程进行了并行数值模拟。气相控制方程组用欧拉坐标系下的Navier-Stokes方程组描述,液相控制方程组在Lagrangian坐标系下进行描述。气、液两相作用通过方程组的源项互相耦合。编制了串行和并行程序,并在并行计算环境下进行了测试。从计算结果可以看出并行计算的效率较高。 |

Abstract: |
The nonlinear combustion instability process in liquid rocket engine is simulated. The gas controlling Navier-Stokes equations are described under the Euler coordinate.The liquid phase controlling equations are described under the Lagrangian coordinate.The two phase influences of gas and liquid are through the sources of equations.The sequential and parallel codes are written,and the codes are tested in parallel virtual machine environment.The results show that the parallel computation efficiency is reeasonably high. |
Keywords: parallel computation nonlinear combustion process liquid rocket engine |
