A numerical investigation has been carried out for coupled partial differential equations which describe varying fluid properties on unsteady, free convective chemically reacting fluid flow on a moving vertical cone and flat plate. The computations for flow, heat, and mass transport in presence of thermal radiation, viscous dissipation, Soret and Dufour effects are carried out using Crank-Nicolson scheme. The influence of active parameters on transport properties of the fluid is displayed in form of graphs and tables. The results elucidate that the consideration of variable fluid properties has a significant influence on the flow, heat and mass transfer characteristics. Strengthening the Casson fluid parameter tends to decelerate the fluid velocity and escalate the local skin friction. © 2019, EDP Sciences, Springer-Verlag GmbH Germany, part of Springer Nature.

Heat and mass transfer in MHD non-Newtonian bio-convection flow over a rotating cone/plate with cross diffusion

The present study focuses on the effects of surface dependent heat source/sink, viscosity and thermal conductivity variations on unsteady flow of Casson fluid over a vertical cone and flat plate with the influence of thermal radiation, temperature dependent heat source/sink and higher order chemical reaction effects. The model which is constituted with highly nonlinear governing equations is solved numerically by an efficient finite difference scheme of Crank-Nicolson type. Numerical calculations are carried out and reported graphically for various parametric conditions to show interesting aspects of the solution on flow, heat and mass transfer characteristics of this problem. Results indicate that the hydrodynamic and thermal boundary layer thickness decrease for higher values of thermal radiation parameter. The fluid flow and heat transfer are appreciably influenced by the temperature dependent heat source/sink parameter. The flow and heat transfer characteristics of this problem are also regulated by surface dependent heat source/sink, viscosity and thermal conductivity variation parameters. © 2016 Elsevier B.V.

Influence of higher order chemical reaction and non-uniform heat source/sink on Casson fluid flow over a vertical cone and flat plate

The present study focuses the effects of double dispersion, non-uniform heat source/sink and higher order chemical reaction on unsteady, free convective, MHD Casson fluid flow over a vertical cone and flat plate saturated with porous medium. The extensively validated and unconditionally stable numerical solutions are obtained for the governing equations of two dimensional boundary layer flow by using the finite difference scheme of Crank-Nicolson type. The behavior of velocity, temperature and concentration distributions for various controlling parameters of this problem are graphically illustrated and discussed in detail. The average skin friction, Nusselt number and Sherwood number for sundry parameters are presented in tables. Results indicate that an increase in Casson fluid parameter is found to decelerate fluid flow by increasing the plastic dynamic viscosity whereas it enhances the shear stress in the flow regime. The temperature-dependent heat source/sink plays a vital role on controlling the heat transfer however the surface-dependent heat source/sink also has notable influence on the heat transfer characteristics. It is to be noted that higher order chemical reaction has the tendency to dilute the influence of chemical reaction parameter on the species concentration.

Unsteady Magnetohydrodynamic Casson Fluid Flow over a Vertical Cone and Flat Plate with Non-Uniform Heat Source/Sink

A study has been carried out to analyze the effects of heat absorption, chemical reaction, and thermo-diffusion on unsteady magnetohydrodynamic (MHD) oscillatory flow of an electrically conducting Casson fluid in a porous asymmetric channel which oscillates subject to time with a constant frequency. The governing equations include the continuity, momentum, energy, and mass transfer equations which are solved analytically by using exact solution method. The features of fluid flow, heat, and mass transfer characteristics are analyzed by plotting graphs and the physical aspects are discussed in detail to interpret the effect of various significant parameters of the problem. The results indicate that solutions of the boundary layer are oscillatory type due to the orientation of the channel. It is observed that the geometric parameters of the asymmetric channel have a notable influence on the fluid flow. © 2015 by Begell House, Inc.
