The aim of this work is scrutinizing the consequences of non-linear radiation on MHD Casson nanofluid along thin needle. The situation has been mathematically modelled taking into account the thermo-diffuso and diffuso-thermo effects. Here two types of surfaces are dealt; one is fixed needle and other is moving needle. The Prandtl boundary layer equations are enclosed and solved numerically using similarity variables. Impact of different material parameters on the momentum, temperature and species concentration along with the quantities related engineering aspects like skin friction coefficient, rate of energy transfer and Sherwood number are obtained and illustrated through graphs. A comparison examination is made between studied Casson nanoflow usage makes the environment cool, reduces the friction at the surface. But Newtonian nanofluid is good for species diffusion. Numerical obtained solutions are contrasted with the published literature and found to be in nice agreement. The present exploration exhibits the prominent features in hybrid solar magneto-hydrodynamic nanofluid systems and aircraft technology. © 2019

Interaction of single and multi walls carbon nanotubes in magnetized-nano Casson fluid over radiated horizontal needle

AbstractPresent analysis is to study the combined effects of viscous dissipation and Joule heating on MHD three-dimensional laminar flow of a viscous incompressible non-linear radiating Casson nanofluid past a nonlinear stretching porous sheet. Present model describes that flow generated by bi-directional non-linear stretching sheet with thermophoresis and Brownian motion effects. The governing nonlinear partial differential equations are transformed into a system of nonlinear coupled ordinary differential equations by similarity transformations and then solved by employing shooting method. The effects of the flow parameters on the velocity, temperature and concentration as well as the skin friction coefficient, Nusselt number and Sherwood number near the wall are computed for various values of the fluid properties. This study reveals that the temperature of Casson nanofluid increases with combination of viscous dissipation and Joule heating. Increasing thermophoresis parameter increases the species concentration of the nanoflow. The comparison of present results have been made with the published work and the results are found to be very good agreement.

Boundary layer analysis of persistent moving horizontal needle in Blasius and Sakiadis magnetohydrodynamic radiative nanofluid flows

The slip and heat transfer effects on MHD peristaltic transport of a nanofluid in a non-uniform symmetric/asymmetric channel have studied under the assumptions of elongated wave length and negligible Reynolds number. From the simplified governing equations, the closed form solutions for velocity, stream function, temperature and concentrations are obtained. Also dual solutions are discussed for symmetric and asymmetric channel cases. The effects of important physical parameters are explained graphically. The slip parameter decreases the fluid velocity in middle of the channel whereas it increases the velocity at the channel walls. Temperature and concentration are decreasing and increasing functions of radiation parameter respectively. Moreover, velocity, temperature and concentrations are high in symmetric channel when compared with asymmetric channel. © 2017 Published under licence by IOP Publishing Ltd.

Brownian motion and thermophoresis effects on Peristaltic slip flow of a MHD nanofluid in a symmetric/asymmetric channel

The three-dimensional magnetohydrodynamic flow and heat transfer of Sisko nanofluid across a bidirectional stretching sheet are examined numerically. Nonlinear thermal radiation is incorporated into the energy equation. The reduced governing PDEs are solved by using the bvp5c Matlab package. The local Nusselt number and wall friction are computed at different pertinent parameters. With the help of graphical illustrations, we studied the momentum and thermal boundary layer behavior. It is found that the flow and thermal boundary layers of Cu-water nanofluid are higher than the methanol-Cu nanofluid. © 2017 Published under licence by IOP Publishing Ltd.
