摘要
本文进行了柴油机管道内3D内流场模拟分析。根据汽车尾气在排气管道内的流动情况,采用定常数值计算,结合二方程k-ε湍流模型,用耦合、隐式格式进行了数值分析。计算结果与实际结果基本吻合。
The three-dimension in-flow field is simulated and analyzed. According to the in-flow of exhaust,adopting the stable-constant numerical computation, combining the two-equation k-6 onflow model, the numerical analysis was carried out. The calculation result is consistent with the true outcome.
