CFD simulation analysis and experimental study on multilobe hydrodynamic journal bearing

Abstract

The multilobe hydrodynamic journal bearing has been analyzed on the basis of the static pressure that developed in the system. The characteristics of four-lobe hydrodynamic journal bearing have conducted by CFD simulation software based on the Navier Stokes equation. The simulation results then validate with the experimental results. The performance of four lobe hydrodynamic journal bearing is superior compared to plain journal bearing at low-speed applications.
