摘要：采用计算流体力学(CFD)技术研究气流脉动,对新气流脉动消减装置内气流流场进行分析,得到了压力的分布规律、切向速度的减小趋势以及气流脉动曲线,并对新的消减脉动装置进行了优化设计。模拟计算结果揭示了装置内部气流流动的基本特征和变化的基本规律,阐明了该装置消除气流脉动的主要机理。
The airflow ripple was investigated by CFD （computational fluid dynamics） technique.After analyzing the flow fields of the device, some parameters, such as distribution of equal pressure surface, the reducing tendency of circumferential velocity, and a curve of airflow ripples were obtained. An optimizing design was engaged for the new device to remove the airflow ripples. The simulating computation reveals the basic features and their changes of the airflow in the device. The primary principles to reduce the airflow ripples were analyzed.
