Dynamics of Soret–Dufour effects and thermal aspects of Joule heating in multiple slips Casson–Williamson nanofluid

Abstract

Recently, the thought of nanotechnology has endowed mankind to create materials of nanometer magnitudes. Nanoparticles or nanomaterials have diverse optical, chemical, thermal and physical possessions from their pre-supremacy corresponding item. Hence, this paper comprises the features of a Casson–Williamson flow field with nanoparticles. Here, we explored the impact of rate slip precondition on the mechanics of heat and mass transport over a stretched sheet with viscous dissipation, and heat generation in an exceedingly porous medium. The influence of Soret–Dufour, magneto-hydrodynamics (MHD) and thermal radiation is presumed. All chemical science specifications of nanofluid are measured as constant. As a result of motion of nanofluid particles, the fluid concentration is inspected underneath chemical implications. A collection of coupled partial differential frameworks is accustomed mathematically to formulate the physical model. The scheme for numerical study named Runge–Kutta approach along with shooting technique is implied to solve the obtained equations. The numerical procedure is then displayed pictorially, where fluid velocity, temperature and concentration against various pertinent parameters are examined. The velocity of the nanofluid encompasses a quicker rate within the deficiency of a magnetic factor; however, the velocity field possesses a reverse trend for Casson factor. The higher Eckert number intensifies the temperature of Casson fluid. Furthermore, the Casson parameter and the velocity slip parameter reduce the drag force and local Nusselt number.
