FLOW VISUALIZATION IN PIVOTED-PAD JOURNAL BEARING

Abstract

Fluid flow in clearance of pivoted-pad journal bearing was visualized. Flow visualization was performed by means of hydrogen bubble method.
The experiments were carried out for parallel and wedge film. In the case of wedge film type, it was observed that Taylor vortices occur from behavior of streak line. Furthermore it was observed that the difference between one pad type and four pads type exists.
