Nano-fluid lubrication of single-layered porous hydrostatic bearing: a theoretical approach

A theoretical framework of single-layered PHB (porous hydrostatic bearing) lubricated by nano-oil has been developed here. The impact of nano-oil on the presentation of said hydrostatic bearing has been concentrated with the assistance of modified Darcy’s law and distinctive boundary conditions. The different nanoparticles are utilized as an added substance of conventional lubricants to upgrade its consistency. The statement of dimensionless exhibition attributes of the researched bearing has been determined by utilizing the modified Krieger–Dougherty viscosity model of nano-fluid and modified Darcy’s flow model. The outcomes uncovered that the exhibition qualities are fundamentally improved with the utilization of nano-lube oil as contrasted and the equivalent of other Newtonian and micropolar fluids. Thus, the present investigation is validated with perfect covenant.
