Original Abstract

The article presents two mathematical models of the interaction between a rotating shaft and an incompressible fluid. The mathematical model includes both the journal bearings and the axially traversed hydrodynamic sealing gaps of hydraulic machines. A method is shown for the identification of additional effects of the fluid acting on the rotor of the machine, both for a linear and a non-linear model. The interaction is expressed by matrices of mass, stiffness and damping.

Keywords

CFD modeling, hydrodynamic gap, matrices of mass, stiffness and damping, nonlinear mathematical model.
