TL;DR: A mass conserving algorithm (Elrod algorithm) which uses the Jakobsson, Floberg, and Olsson cavitation boundary conditions has been implemented to analyze crankshaft bearings as discussed by the authors.
Abstract: A mass conserving algorithm (Elrod algorithm) which uses the Jakobsson, Floberg, and Olsson cavitation boundary conditions has been implemented to analyze crankshaft bearings. The main and connecting rod bearings of a typical automotive engine are considered. Some sample steady-state results are presented. The inverse problem (given the load, find the journal orbit) is solved for real engine loads. Comparisons are made with a non-conservative algorithm based on the Reynolds boundary condition. Significant differences in the cavitation zones and oil flows are observed between the two algorithms. In all cases, the oil flow into the bearing is found to match the oil flow out of the bearing for the Elrod algorithm. Presented at the 44th Annual Meeting in Atlanta, Georgia May 1–4, 1989

TL;DR: In this paper, the alternating direction implicit (ADI) method is used to numerically solve a single partial differential equation that is valid throughout the bearing, i.e., both in full film and cavitated regions.
Abstract: A numerical investigation of gaseous cavitation in noncircular journal bearings of finite length is presented in this paper. Four bearing profiles are considered: circular, worn-circular, two-lobe (lemon) and elliptical. The alternating direction implicit (ADI) method is used to numerically solve a single partial differential equation that is valid throughout the bearing, i.e., both in full film and cavitated regions. The equation is part of the Elrod algorithm which is used to simulate bearing cavitation. This procedure, which conserves mass throughout the bearing, automatically implements boundary conditions at rupture and reformation that are thought to model moderately to heavily loaded bearings. Performance predictions are compared to results obtained from a variety of earlier papers. Presented at the 43rd Annual Meeting in Cleveland, Ohio May 9–12, 1988

TL;DR: In this article, the authors considered transient radiative and conductive heat transfer in a rectangular, absorbing-emitting and isotropically scattering medium and applied an integral-equation method and a modified differential approximation to the radiation part of the present problem.

TL;DR: In this article, an axi-symmetric, time-dependent simulation of the piston ring-cylinder contact was used to investigate the optimum surface texture of a piston ring.
Abstract: Many simulations already exist to model the piston ring–cylinder liner contact; however, very few models have been used to investigate the optimum surface texture. An axi-symmetric, time-dependent ...
