STEADY STATE CHARACTERISTICS OF FINITE HYDRODYNAMIC POROUS OIL JOURNAL BEARING UNDER TURBULENT REGIME

Abstract: In this paper theoretical investigation of steady state characteristics of finite hydrodynamic porous oil journal bearing under turbulent regime has been conducted. Governing equation is solved numerically by using finite difference technique. Constantinescu's turbulent lubrication theory is used for this analysis. The steady state characteristics such as load carrying capacity, friction variable, end flow rate and attitude angle have been investigated over a broad span of variables like Reynolds's number, eccentricity ratio, slenderness ratio and bearing speed parameter. These characteristics are numerically evaluated using Borland C++ software for windows 7 operating system. The results are denoted by graphs which can be convenient for the analysis of such bearings.
