Evaluation of viscous force effects on rotor of squeeze film damper using newtonian and non-newtonian fluid

Abstract
Presents mainscript mainly deals with the evaluation of force effects on
rotor of squeeze film damper. Rotor is eccentric placed and its motion is
translate-circular. The amplitude of rotor motion is smaller than its initial
eccentricity. The force effects are calculated from pressure and viscous forces
which were gained by using computational modeling. Two types of fluid were
considered as filling of damper. First type of fluid is Newtonian (has constant
viscosity) and second type is magnetorheological fluid (does not have constant
viscosity). Viscosity of non-Newtonian fluid is given using Bingham rheology
model. Yield stress is a function of magnetic induction which is described by
many variables. The most important variables of magnetic induction are electric
current and gap width which is between rotor and stator. Comparison of
application two given types of fluids is shown in results.
