Abstract
•A theoretical structure for stagnation point flow along a wavy circular cylinder with magnetic field effects are presented.•Momentum and thermal boundary layer are developed by introducing the nanofluid model.•Expression of effective thermal conductivity and viscosity are introduced.•Skin friction provides the increasing behaviour with respect to increase of nanoparticles.•Heat transfer rate for Cu delivers the better thermal conductivity as compare to other particles.
In the present study, simultaneous effects of metallic nanoparticles and magnetohydrodynamic due to stagnation point flow of nanofluid along a wave circular cylinder is presented. The effect of induced magnetic field is incorporated to deal the boundary and thermal boundary layer domain. Mathematical modelling for momentum and energy equation is constructed that is based upon three different kinds of nanoparticles namely: copper (Cu), Titanium di oxide (TiO2), and alumina (Al2O3) within the working fluid water. Each mixture is analysed at the individual level and made comparison amongst all the mixture to examine the resistance and thermal conductivity of nanofluid within the boundary layer region. The solutions are exposed via boundary value problem using shooting method along with the Runge-Kutta-Fehlberg method. The characteristics of emerging parameters for the fluid flow and heat transfer are discussed through graphs and tables. The effects of ϕ (nanoparticle volume fraction) on heat transfer and shear stress at the wall are analysed in detail. It is finally concluded that by increasing the ratio of nanoparticles there is a significant increase in the temperature but slight decrease in the velocity profile.
Model is intended to describe the effects of copper (Cu), Titanium di oxide (TiO2), and alumina (Al2O3) on MHD flow of nanofluid along a circular cylinder. [Display omitted]
