Overview

Model demonstrates cavitation and temporal discretization in fluid-structure interaction, implying stable bearing performance.

Key Points

  • To characterize the pressure field of a liquid-gas lubricant mixture and study cavitation effects in hydrodynamic bearings.
  • Implemented a novel model from first principles for pressure field characterization
  • Utilized high resolution schemes for spatial treatment
  • Applied temporal discretization based on Strang splitting method
  • Studied cases involving textures, temperature interaction, and solid-fluid resonance
  • Model captures Oil Whirl and Oil Whip instabilities
  • Demonstrates changes in textures enhance pumping effect
  • Addresses temperature increases due to friction alongside cavitation
