| 摘 要： | 该文运用色噪声扩维方法和统一色噪声方法的矩模型／有限体积／SIMPLE方法数值模拟旋流燃烧器旋转两相流动。与k-ε-kp模型的模拟结果相比，颗粒相速度有明显的改善，特别是壁面附近与实验结果吻合得更好。两个模型相比，色噪声扩维方法轴向小，与实验吻合得好，切向和径向偏大，低于实验结果；而统一色噪声方法相反，总体比较，色噪声扩维方法优于统一色噪声方法。

| Abstract: | The moment closure model for colored noise dimension expanding（CNDE） method and united colored noise（UCN） method are employed to simulate the swirl two- phase flow with finite volume/SIMPLE method. Compared with the results by k - ？ - kp model, the simulating results is better, especially the particle velocity by wall. The simulations results of CNDE is better than of UCN, the particle axis velocity by CNDE is agrees with the experimental results and lower than by UCN, but the tangential and vertical velocity by CNDE is higher than that by UCN, and lower than the experimental results. |
