Squeeze-film narrow porous journal bearings lubricated with a micropolar fluid

Squeeze-film narrow porous journal bearings using a lubricant containing solid particle additives and characterized as a micropolar fluid were analysed. The load capacity and time of approach increase as the micropolar parameter characterizing the concentration of the microstructure imparted to the lubricant by the additives increases. The load capacity and time of approach decrease as the permeability and/or the thickness of the porous wall increases.
