摘要
利用数值模拟软件Ansys建立罗茨鼓风机的二维计算模型,采用动网格技术,使用标准的RNG湍流模型对典型的罗茨鼓风机的内部流场进行了动态模拟,得到的不同时间和位置时风机的速度、压强分布情况,为罗茨鼓风机优化设计和性能预测提供参考。
In this paper, a 2-D computational model of Roots blower was established using Ansys, the dynamical simulation of flow field was performed by using dynamic mesh technique and standard RNG turbulence model. The velocity and pressure distribution in dif- ferent time and positions of flow field in Roots blower were obtained, which could provide reference for design optimization as well as predic- tion of the performance.
