摘要
基于大间隙环流中转子运动的理论模型 ,应用数值方法研究了流体机械中浸在大间隙环流中偏心转子的动力学特性。研究结果表明 :惯性耦合动力学效应已不可忽略 ;偏心率、转子转速及壁面粗糙度等参数是影响大间隙环流中偏心转子动力学特性的重要参数。图 4参
In this paper, a numerical method, based on the theoretical model developed by author in Ref.1, is put forward and employed to analyze dynamic characteristics of eccentric rotor immersed in annular liquid flow of large gap annuli. The simulation results show that the dynamic effect of inertial coupling can not be omitted in this kind annular flow, and the eccentricity ratio, rotor rotation speed and wall roughness have great effects on dynamic characteristic coefficients. Figs 4 and refs 4.
