Numerical analysis of axial compression impact on the hydrodynamics of open-cell foams
Résumé
eX-Poro-HydroDynamique lubrication (or XPHD lubrication) presents a different scientific
approach to dealing with tribological problems. It’s an innovative inter- and ultidisciplinary research topic which offers a promising sliding solution for various applications, such as bearings, thrust bearings, various guide components, etc. Its applications in both biological systems, and industrial systems: soft porous squeeze damping or soft porous lubrication are very broad and important. XPHD lubrication is a lubrication mechanism of biomimetic inspiration which features an additional parameter to the system “the porous media”. It consists of self-sustained fluid films generated within compressible porous layers (CPL) imbibed with liquids in replacement for using the fluid film only as in the classic lubrication system. he numerical simulations of flows will be performed with the solvers icoFoam and simpleFoam of the OpenFOAM framework for steady-state incompressible laminar and turbulent flows, making it possible to study different fluids and porous materials. The performed simulations were made with an open-pore polyurethane foam with 96% porosity using five compression rates for creating the different geometries.
