TL;DR: In this article, the impact of the cavitation model on the numerical assessment of lubricated journal bearings is analyzed and compared using the classical Reynolds model and the so-called p- θ model proposed by Elrod and Adams.

TL;DR: A numerical algorithm for fully dynamical lubrication problems based on the Elrod-Adams formulation of the Reynolds equation with mass-conserving boundary conditions is described in this article, where a simple but effective relaxation scheme is used to update the solution maintaining the complementarity conditions on the variables that represent the pressure and fluid fraction.

TL;DR: It is shown that the adaptive algorithm that results recovers optimal convergence rates in singular problems, and that it captures boundary and internal layers in convection-dominated problems.

TL;DR: A numerical method to approximate partial differential equations on meshes that do not conform to the domain boundaries is introduced and, by virtue of relaxing the continuity constraint at those elements, boundary locking is avoided and optimal‐order convergence is achieved.

TL;DR: In this article, a mathematical model for dilute bubble plumes is derived from the two-fluid model equations, coupled with a mass transfer model to get a closed CFD formulation.
