【摘要】 以气体湍流运动的微分方程组及 ｋε湍流模型为基础，采用 Ｓ Ｉ Ｍ Ｐ Ｌ Ｅ 算法数值模拟研究了气体涡旋燃烧器中的三维旋转湍流场。旋转方向的迭代采用了 Ｃ Ｔ Ｄ Ｍ Ａ 方法，计算收敛速度明显加快。预测结果与日本古火田朋彦的 Ｌ Ｄ Ｖ 冷模实测值吻合较好。更多还原

【Abstract】 The three dimensional turbulent field in the gas vortex combustor had been studied by SIMPLE numerical calculation based on turbulent differential equations and \%k ε\% model. Owing to the use of the cyclic tri diagonal matrix algorithm (CTMDA) in the rotating iterative direction, the rate of convergence is evidently faster. The predicated results compared with Tomohiko Furuhata′s experimental values of LDV cold model is very good.更多还原
