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

Aerodynamic Interference between Oscillating Lifting Surfaces and Fuselage. Part 6: A Panel Method for Non-Lifting Bodies Oscillating in Subsonic Flow [PDF]
In the sixth part of this series, we continue our study started in the previous article, i.e., we present the basis of the method for calculating the unsteady airforces on oscillating non-lifting bodies. The method proposed here is a panel one.
