Ree-Eyring fluid flow of Cu-water nanofluid between infinite spinning disks with an effect of thermal radiation

We analyzed the Ree-Eyring fluid flow between two stretchable spinning disk with various stretching rates along with copper-water nanoliquids. An impact of thermophoresis and Brownian motion and thermal radiation effect also investigated properly. Appropriate transformations are applied to change highly coupled non-linear system of PDE to coupled ODE associate with convective boundary conditions, which is then attained numerically via utilizing Runge-Kutta-Felberg method with shooting technique. The behavior of significant parameters on the distribution function of temperature, concentration and velocity has been clarified via sketch in detail. Clearly, It is carried out that the Brownian motion parameter Nb elevates by more heat produced via collision of nanoparticles randomly. So field of temperature and boundary layer thickness also enlarged. Lastly, heat transfer rate hikes at upper one as well as decays at lower one along with large amount of Weissenberg number and thermophoresis parameter respectively. The outputs are estimated with previously published work and found to be an excellent conformity. (C) 2021 THE AUTHORS.
