A numerical procedure to predict the effects of gaseous cavitation in moderately to heavily
loaded bearings is developed. The method is an outgrowth of the Elrod algorithm which is
simple to use and which automatically implements cavitation boundary conditions at film
rupture and reformation. The current procedure makes use of type differencing in the shear
induced flow formulation to automatically switch from central to upwind differences, and vice
versa, at cavitation boundaries. Comparison is made with the results obtained using Elrod's …

The current procedure makes use of type differencing in the shear induced flow formulation to automatically switch from central to upwind differences, and vice versa, at cavitation boundaries. Comparison is made with the results obtained using Elrod's algorithm for various test cases involving both slider and journal bearings.
