Approximate analytical solution to Reynolds equation for finite length journal bearings
(Elsevier, 2011-09)
The understanding of the behavior of hydrodynamic bearings requires the analysis of the fluid film between two solid surfaces in relative motion. The differential equation that governs the movement of this fluid, called ...
Do transience gravity waves in a shear flow break?
(John Wiley & Sons Ltd, 2008-07-10)
The propagation of transient gravity waves in a shear flow towards their critical levels is examined using a ray tracing approximation and a higher-degree (quasi-optic) approximation. Because of its transient forcing, the ...
