The Effects of a Thin Liquid Layer on the Hydrodynamic Machine Rotor

Authors: František Pochylý, Jaroslav Krutil, Simona Fialová, Vladimír Habán

Abstract:

A mathematical model of the additional effects of the liquid in the hydrodynamic gap is presented in the paper. An incompressible viscous fluid is considered. Based on computational modeling are determined the matrices of mass, stiffness and damping. The mathematical model is experimentally verified.

Keywords: Computational Modeling, mathematical model, hydrodynamic gap, matrices of mass, stiffness and damping
