| 摘要: |
| 文中以SIMPLE方法为基础,采用k-ε两方程湍流模型,发展了一种模拟燃烧室内三维湍流内流场的数值计算方法和计算程序。通过对四种冷流状态进行数字模拟,初步结果表明,理论计算与已有实验结果一致性良好。 |

| Abstract: |
| Based on SIMPLE method, a numerical method and a com-puter program are developed to simulate flows in combustion chambers. The flows in combustion chambers with tilm cooling slots and secondary air holes are numerically simulated under different conditions. The results are in good accordance with experimental results. |
