| Abstract: | A simplified numerical method was put forward in order to analyze the characteristics of an eccentric rotor in a finite-length annular flow of large gap annuli.Dynamic coefficients of 3D finite-length eccentric annular flow of large gap annuli were calculated by using the simplified method,which was based on the analysis of finite-length concentric annular flow of large gap annuli.Comparing with an existing numerical method for getting numerical results and experimental results of the dynamic coefficients o... |
