摘要
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 multi dimensional two phase spray combustion process in liquid rocket engine was simulated.The gas controlling equations were described under the Euler coordinate.The liquid phase controlling equations were described under the Lagranginan coordinate.The two phase influences of gas and liquid were considered through the sources of equations.The sequential and parallel codes were written and were tested under parallel virtual machine environment.The results showed that parallel computation efficiency was reasonable
