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。
Based on SIMPLE method, a k-ε two-equation turbulence model is developed to develop a numerical method and calculation program to simulate the 3D turbulent flow field in a combustion chamber. Through the numerical simulation of four cold flow conditions, the preliminary results show that the theoretical calculation is in good agreement with the existing experimental results.
