Analytical fluid film force in the turbulent journal bearings

D'Agostino V., Guida D., Ruggiero A.

Vol. 4, no spec.

The aim of this paper is to illustrate a method to determine the analytical description of non-steady fluid film force and of the stiffness and damping coefficients for the "short" liquid-lubricated journal bearings in a fully developed turbulent flow regime. The equation goveming the distribution of pressure around the bearing has been solved analytically; the models has been developed assuming lubricant flow is isoviscous.
