Abstract

The effect of small, spherical, rigid particles, droplets or bubbles (henceforth referred to as particles) on the performance of a hydrodynamic bearing is theoretically investigated. A low Reynolds number solution for a single particle is utilized to obtain the integrated effect of a dilute suspension. Two examples are addressed: a long Rayleigh step slider and a long journal bearing. It is found that load-carrying capacity is negligibly affected by the presence of the particles, whereas the friction is increased appreciably. Presented at the 41st Annual Meeting in Toronto, Ontario, Canada May 12–15, 1986
