Non-Newtonian lubrication with Rabinowitsch fluid: a theoretical study on rough step slider bearings [PDF]

open access: yesScientific Reports
This study investigates the performance of a step slider bearing lubricated with Rabinowitsch fluid considering a rough bearing surface. The influence of surface roughness is analyzed using Christensen’s theory, while the fluid film pressure is ...

A numerical solution for the equation of the lifting surface in subsonic flow including tunnel effects [PDF]

open access: yesINCAS Bulletin, 2011
We employ the images method to establish the lifting surface equation including tunnel effects. We obtain a 2d hypersingular integral and we utilize Gauss-type quadrature formulas to discretize it.
