Thermophoresis and Brownian motion effects on unsteady MHD nanofluid flow over a slendering stretching surface with slip effects

In this paper, we analyzed the mathematical model of the convective conditions on Casson fluid across a Paraboloid of Revolution (PR) in the presence of pertinent parameters like magnetic field parameter, Soret, and Dufour. We used R-K-Felhberg-integration scheme based shooting technique to solve the modified governing equations and discussed the appearance of curious parameters on the profiles velocity, temperature and concentration profiles in three cases n = 0, n = 0.5 and n = 1 with the aid of plots. We found that the profiles of velocity, temperature, and concentration are non-uniform for all these three cases. Also, we have taken the help of tables to explore the skin friction coefficient, local Nusselt and Sherwood numbers, which are useful for the purpose of engineering interest. It is noticed that the cross diffusion helps to control the thermal, diffusion and momentum boundary layers for all the three cases. The mixed convective conditions are useful in improving the heat and mass transport phenomena. We also validated the present methodology with already existing methodologies under some limited cases. © 2018 Faculty of Engineering, Alexandria University

MHD Casson fluid in a suspension of convective conditions and cross diffusion across a surface of paraboloid of revolution

This paper numerically analyses thermo diffusion effects on MHD Casson fluid flow over a stretching sheet with variable thickness. Cattaneo–Christov heat flux model is imposed to predict the effects of thermal relaxation time. Similarity transformation is employed to normalise the governing boundary layer equations. Keller box method is applied to solve the system of equations. The behaviour of emerging parameters, such as Casson parameter ((Formula presented.)), Magnetic parameter ((Formula presented.)), power index ((Formula presented.)), variable viscosity parameter ((Formula presented.)), Prandtl number ((Formula presented.)), Soret number ((Formula presented.)) and Schmidt number ((Formula presented.)) on velocity, temperature and concentration distributions, are discussed and analysed graphically. It is found that temperature profile decreases for large entries of thermal relaxation parameter. The concentration boundary layer thickness increases for large entries of Soret number. © 2018 Informa UK Limited, trading as Taylor &amp; Francis Group.

Thermo diffusion effects on MHD Casson fluid flow over non-flatness stretching surface: Keller box method

A numerical analysis is performed for investigating the slip flow of a viscous dissipative Casson fluid towards a stretching sheet with Cattaneo-Christov heat flux and variable viscosity. The nonlinear partial differential equations are transformed with appropriate similarity variables into a system of nonlinear ordinary differential equations. Numerical solutions are carried out by using efficient Spectral relaxation method. Notable accuracy of the present results has been obtained with previous results in a limiting sense from the literature. It is found that thermal relaxation time has an inverse relationship with the fluid temperature. Interestingly, the fluid velocity is gradually decreasing with higher values of slip factor.

Slip Velocity and Temperature Jump on Dissipative CASSON Fluid with CATTANEO-CHRISTOV Heat Flux Model: Spectral Relaxation Method

The two-dimensional unsteady magnetohydrodynamic squeezing flow and heat transfer of Casson fluid between two parallel plates with aligned magnetic field and nonlinear thermal radiation is investigated theoretically. The resulting governing equations are transformed as set of ODEs and solved numerically by using bvp4c Matlab package. The influence of various pertinent parameters on the flow and temperature fields are discussed with the assistance of graphical illustrations. The reduced Nusselt number are presented through graphs. It is seen that increasing values of squeeze number depreciate the flow and temperature fields.

Effect of Aligned Magnetic Field on MHD Squeezing Flow of Casson Fluid between Parallel Plates

The objective of this paper is to analyze the influence of thermal radiation and chemical reaction on the boundary layer flow of a magnetohydrodynamic Jeffrey nanofluid over a permeable cone in the presence of thermophoresis, Brownian motion effects. The set of non-linear governing partial differential equations are transformed into set of non-linear coupled ordinary differential equations by using self-suitable transformations, which are then solved numerically using Runge-Kutta fourth order along with shooting technique. The obtained results present the effects of various non-dimensional governing parameters on velocity, temperature and concentration profiles. Also, enumerated and analyzed the friction factor, local Nusselt and Sherwood numbers. We presented dual solutions in the presence and absence of the magneticfield and found an excellent agreement of the present results with the existed studies under some special limited cases. Result indicates that an increase in the buoyancy parameter increases the heat and mass transfer rate in the presence and absence of the transverse magneticfield and dual solutions exists only for certain range of magneticfield parameter.
