Study on Two Phase Flow Heat Transfer of High Speed Bearings by Injection Lubrication

Abstract

In this paper, the study of Numerical analysis of bearing lubrication flow field is presented. Through the experiment, due to the centrifugal force, the liquid diffusion of a uniform surface. when v=1094mm/s, the whole surface has smaller accumulation of fluid film thickness of thicker body, this condition is not conducive to the ball body heat, proper ball rolling speed can in the fluid diffusion into the surface of the ball. Without contact with the stationary samples, the fluid diffusion area. And when the rolling ball contact with the stationary sample, the liquid will be together, the radius is smaller, the fluid gathered more concentrated, which is not conducive to the rolling lubrication and cooling.
