| 摘 要： | 应用新的ＰＩＳＯ算法对液体火箭发动机内非定常流动过程进行了数值模拟计算。算法采用一步隐式预测、两步显式校正完成每一时间层计算，而不是通常的多次迭代计算，因而大大缩短计算时间。

| Abstract: | Numerical simulation of unsteady flow in liquid propellant rocket engine is performed with a new PISO algorithm in the present paper. The algorithm yields approximate solutions of the differential equation with one predictor step and two corrector steps at each time level instead of iteration calculation. Therefore,the CPU time cost in the calculation is reduced greatly which made numerical simulations of unsteady flow become practicable. |
