Physical aspects of magnetized suspended nanoparticles in a rotatory frame: Numerical simulation

Abstract

The non-Newtonian liquid named Casson towards rigid rotating disk is investigated. The rotatory fluid flow regime has interaction with externally applied magnetic field. The nanoparticles are suspended in the flow field along with first order chemical reaction and velocity slip assumption. The flow narrating partial differential equations are reduced in terms of an ordinary differential equations via Von Karman set of transformations. The reduced system is solved by self-coded algorithm. The impacts of flow controlling parameters which includes the magnetic field parameter, Casson fluid parameter, velocity slip parameter, thermophoresis parameter, Prandtl number, Lewis number, Brownian motion parameter and chemical reaction parameter are examined on Casson fluid velocity, temperature and nanoparticles concentration. It is observed that the rotatory Casson fluid reflects significant decline in a magnetized flow field. The temperature is increasing function of thermophoresis parameter. Further, the results are supported with comparative values with an existing work.
