采用计算流体动力学方法对液体火箭发动机内部多维喷雾两相燃烧过程进行了数值模拟。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,并在并行虚拟机环境下进行了测试。计算结果显示并行计算的效率较高。
The computational fluid dynamics (CFD) method was used to simulate the multi-dimensional spray two-phase combustion in a liquid rocket engine. The gas-phase control equations are described by the Navier-Stokes equations in the Eulerian coordinate system and the liquid-phase control equations are described in the Lagrangian coordinate system. The gas-liquid two-phase interaction is coupled with each other through the source terms of the equations. Serial and parallel programs are prepared and tested in a parallel virtual machine environment. The results show that parallel computing is more efficient.
