Current disquisition is presented to excogitate heat and mass transfer features of second grade fluid flow generated by an inclined cylinder under the appliance of diffusion, radiative heat flux, convective and Joule heating effects. Mathematical modelling containing constitutive expressions by obliging fundamental conservation laws are constructed in the form of partial differential equations. Afterwards, transformations are implemented to convert the attained partial differential system into ordinary differential equations. An implicit finite difference method known as the Keller Box was chosen to extract the solution. The impact of the flow-controlling variables on velocity, temperature and concentration profiles are evaluated through graphical visualizations. Variations in skin friction, heat transfer and mass flux coefficients against primitive variables are manipulated through numerical data. It is inferred from the analysis that velocity of fluid increases for incrementing magnitude of viscoelastic parameter and curvature parameter whereas it reduces for Darcy parameter whereas skin friction coefficient decreases against curvature parameter. Assurance of present work is manifested by constructing comparison with previous published literature.

The Impact

We analyze the impact of suction/injection on MHD convective oscillatory flow of second grade fluid through a Porous Medium in a vertical channel with non-uniform wall temperature. The liquid is occupied with a transverse Magnetic field and the velocity slip at the left plate is taken into consideration. The precise solutions of the dimensionless equations are obtained and the effects of the flow parameters on velocity, temperature and concentration profiles, skin friction and rates of heat and mass transfer are discussed. It is fascinating to take note of that skin friction increases on together channel plates as permeability increases.

Abstract The investigation deals with the combined heat and mass transfer in a mixed convection boundary layer flow over a stretching vertical surface in a porous medium filled with a viscoelastic second grade fluid. The partial differential equations governing the model have been transformed by a similarity transformation and the system of coupled-ordinary differential equations is solved by employing the shooting method with the fifth-order Runge-Kutta-Fehlberg iteration technique. Effects of various values of physical parameters embedded in the flow model on the dimensionless velocity, temperature and concentration distributions are discussed and shown with the aid of graphs. Numerical values of physical quantities, such as the local skin-coefficient, local Nusselt number and local Sherwood number are presented in a tabular form. It is observed that the boundary layer fluid velocity increases as the second grade parameter, mixed convection parameter and Prandtl number increase.

AbstractThis investigation analyses a three dimensional flow and mass transfer of a second grade fluid over a porous stretching wall in the presence of suction or injection. The equations governing the flow are attained in terms of partial differential equations. A similarity transformation has been utilized for the transformation of partial differential equations into the ordinary differential equations. The solutions of the nonlinear systems are given by the homotopy analysis method (HAM). A comparative study with the previous results of a viscous fluid has been made. The convergence of the series solution has also been considered explicitly. The influence of admissible parameters on the flows is delineated through graphs and appropriate results are presented. In addition, it is found that instantaneous suction and injection reduce viscous drag on the stretching sheet. It is also shown that suction or injection of a fluid through the surface is an example of mass transfer and it can change the flow field.

This paper deals with the examination effect of Dufour and Soret Effect on MHD heat and mass transfer with radiative heat flux in a liquid over a rotating dick. The problem is solved by HAM (Homotopy Analysis Method). The arrangement of Non-Linear Partial Differential Equations (PDEs) which administer the stream, heat and mass exchange qualities is changed into Ordinary Differential Equations (ODEs). It is discovered from the current exploration that Dufour and radiation impacts cause diminishments in the liquid temperature. The effect of suction diminishes the speed, temperature, what’s more, focus profiles essentially in the limit layer.
