Summary :
|
|
ABSTRACT. AN EFFICIENT AND ACCURATE FINITE ELEMENT PROCEDURE, BASED ON THE GALERKIN WEIGHTED RESIDUAL METHOD AND A NOVEL FAMILY OF HIGH-ORDER SHAPE FUNCTIONS, IS DEVISED TO MODEL HIGH SPEED THIN FILM GAS FLOWS. THE NOVEL PROCEDURE PERFORMS AS EFFICIENTLY AS UPWIND FINITE ELEMENT METHODS DEVELOPED FOR HIGH SPEED GAS BEARINGS WITHOUT INTRODUCING NUMERICAL DIFFUSION INTO THE SOLUTION. THE COMPUTATIONAL EFFICIENCY AND ACCURACY OF THE NOVEL HIGH-ORDER FINITE ELEMENT PROCEDURE ARE EVALUATED FOR PLANE SLIDER AND RAYLEIGH STEP GAS BEARINGS.
KEYWORDS: GAS BEARING, HIGH SPEED, UPWIND METHODS
