SCROLL COMPRESSOR: THRUST BEARING DESIGN UNDER LAMINAR CONDITIONS.

Author(s) : KULKARNI S. S.

Summary

THE PAPER PRESENTS THE RESULTS OF A STUDY OF THE SCROLL COMPRESSOR ORBITING THRUST BEARING. THE BOUNDARY CONDITIONS HAVE BEEN DERIVED FOR THE ORBITING MOTION AT THE BEARING SURFACES. A REYNOLDS EQUATION UNDER INCOMPRESSIBLE LAMINAR CONDITIONS WITH CONSTANT VISCOSITY IS DERIVED FROM THE NAVIER-STOKES EQUATIONS. THE EFFECTS OF THE SQUEEZE FILM VELOCITY IS CONSIDERED. THE EQUATION IS SOLVED BY FINITE DIFFERENCE METHODS. FOR A GIVEN AVERAGE FILM THICKNESS AND ATTITUDE ANGLE OF THE SCROLL PLATE, A PRESSURE PROFILE IN THE BEARING FILM IS GENERATED. THE RESULTANT FORCE AND TILTING MOMENT DEVELOPED IN THE BEARING ARE THEN COMPUTED.
