Species and thermal radiation on micropolar hydromagnetic dusty fluid flow across a paraboloid revolution

Abstract

Hydromagnetic flow of energy and species transfer behaviour of micropolar dusty fluid across a paraboloid revolution has been investigated. Heat and mass transfer phenomena are inspected through radiation, joule heating and chemical reaction. The boundary layer equations are modelled and transformed to a system of ODE’S with the aid of similarity transformations and solved numerically by utilizing Runge–Kutta integration scheme. The graphical analysis has been emphasized for the fluid and dust phase velocity, angular velocity, energy and species fields to the influence of sundry dynamical flow quantities. In addition, friction factor, Nusselt number and Sherwood number are presented in plots and tables and discussed elaborately and nice validation is emphasized. The obtained numerical results are checked with the earlier published articles. The boundary layers of angular velocity, temperature and concentration distributions increase for escalating values of magnetic parameter. For escalating values of material parameter, velocity profile increases for both momentum velocity and dusty velocity and opposite trend is seen in angular velocity profile. Concentration and boundary layer thickness diminish for escalating values of kr. Local friction factor declines for boost up values of magnetic parameter and porosity permeability parameter. The rate of heat transfer decreases for increasing values of Eckert number and radiation parameter, and rate of mass transfer increases for increasing values of Schmidt number and chemical reaction parameter.
