Melting and viscous dissipation effects on MHD flow over a moving surface with constant heat source

This article studies , the effects of unsteady magneto-hydrodynamic boundary layer when cobalt nanoparticles where passed onto a vertical plate which is given an impulse by exponential acceleration through porous medium of ethylene glycol when thermal radiation is present ,parameters of absorption of heat and radiation, chemical reaction parameter, magnetic field in transverse direction are theoretically studied. We consider cobalt nanoparticles resembles to spherical structure and range of volume of nanoparticle concentration is basically less than or equal to 4%. Considering the boundary conditions we have formulated a governing equations of nanoparticles which is in the form of partial differential equations. The precise solutions for velocity, concentration and temperature profiles are obtained by plotting the graphs of the equations formed using Laplace Method using MATLAB software. This study of heat transfer in nanoparticles finds application in tribological aspect, biological fields dealing with molecular level cell interactions, improving thermal conductivity and commercial cooling applications. The most significant outcome of this study is found in the concentration profile where time is varied. We see that there is 68% decrease in concentration when the time interval chosen is 0.2, whereas the decrease is found to 55% when the interval is increased to 0.4 keeping the distance from vertical plate constant.

Unsteady MHD Free Convection by Passing Cobalt Nanoparticles Past an Accelerated Vertical Plate Through Porous Medium of Ethylene Glycol

A mathematical model is established to examine the influence of viscous dissipation and joule heating on magnetohydrodynamic (MHD) flow of an incompressible viscoelastic nanofluid over a convectively heated stretching sheet. Brownian motion and thermophoresis effects have been introduced in this nanofluid model. The governing equations are transformed into ODE’s by using suitable similarity conversions and are then solved numerically by the most robust shooting technique. The significance of numerous physical flow constraints is performed for, and distributions through graphs. It is noticed that, the increases for higher values of and reduces for rising values of heat source and Biot numbers. An outstanding contract was found between our numerical results and previously publicised results.

MHD Stagnation Point Flow of Viscoelastic Nanofluid Past a Convectively Heated Stretching Surface

This paper deals with the MHD oscillatory flow of an incompressible and electrically conducting visco-elastic fluid in a vertical channel in the presence of chemical reaction and heat source. The unsteadiness in the flow is due to an oscillatory pressure gradient across the ends of the channel. A closed form solutions for velocity, temperature and concentration profiles as well as skin friction coefficient, rate of heat and mass transfers are obtained by using appropriate mathematical techniques. The analytical outcomes are assessed numerically and then are presented graphically to confer the effects of diverse parameters arriving in the problem. It is witnessed that the fluid velocity profile is parabolic in nature with extreme scale along the channel centerline and least at the walls and therefore, the oscillatory flow enhance the heat transport system by various magnitudes as compared with normal conduction. © 2017, Springer (India) Private Ltd.
