摘要
本文根据Hirs的紊流整体流动理论,研究了离心泵间隙密封的动量方程式,在此基础上,推导了计算动力学系数的微分方程组。
The momental equations of annular seals employed in a centrifugal pump are analyzed based on Hirs'bulk-flow theory for turbulence in this paper. Expressions which define dynamic coefficients for annular seals are also derived. Calculations in numerical method and comparisons are carried out too by the authors.
