MHD radiative ohmic heating nanofluid flow of a stretching penetrable wedge: A numerical analysis

Abstract

The present numerical investigation has focused on the magnetohydrodynamics flow of a viscous nanofluid over a stretching wedge with the boundary convective conditions, thermal radiation, and ohmic heating. Buongiorno's two‐component nonhomogeneous nanoscale model was used and a dilute nanofluid with spherical type particles is considered. Similarity transformations are used to render the system of governing partial differential equations into a system of coupled similarity equations. The transformed equations are solved numerically with the BVP4C method. Validation of solutions with previous studies based on special cases of the general model is included. The salient features of fluid velocity profile, temperature as well as concentration profiles are discussed in a graphical manner for various values of selected governing factors. The skin friction coefficient, mass, and heat transfer rates are calculated and summarized. It is worthwhile noticing that the validation results exhibit an excellent agreement with already existing reports. The modeling of the present problem is useful in the thermal processing of sheet‐like substances that is a necessary operation in paper procurement, wire drawing, drawing of plastic films, polymeric sheets, and metal spinning.

Rheological study of Hall current and slip boundary conditions on fluid–nanoparticle phases in a convergent channel

“…Aljohani et al 5 chose a fractional derivative approach to show the applications of different types of nanoparticles in solar collectors to store solar energy. Some important results of nanofluids in different configurations were also reported by Dharmaiah et al 6–8 and Vedavathi et al 9…”
