摘要：

In this article, a mathematical model of single layered nanofluid lubricated porous journal bearing (PJB) has been formulated. The nano-lubricant's impact on the efficiency of said journal bearing has been studied using modified Darcy's law and boundary conditions. The different nanoparticles often used as an additive in industrial lubricating oils improve their viscosity significantly. The brief description of dimensionless performance characteristics of the investigated bearing was obtained by the use of the nano-lubricant's modified Krieger-Dougherty viscosity model. The observations reveal that the output characteristics are substantially improved by using nano-lubricant. The present study is validated by comparing the findings of recently published data with micropolar fluid and is found to be completely compatible since data with nano-lubricant are still unavailable.
