A theoretical study is conducted to investigate the thermal radiation effect on boundary layer flow of magneto-hydrodynamic (MHD) Jeffrey nanofluid across a moving plate with convective boundary condition. More physically acceptable model of passively controlled wall nanoparticle concentration is executed. Similarity transformation variables are utilised to transform the partial differential equations to non-linear ordinary differential equations. An effective Runge-Kutta Fehlberg Fourth-Fifth order (RKF45) method is employed to solve the obtained equations numerically. Validation of the present results has been made with the existing studies under the limiting cases and the results are found to be in a good agreement. Numerical solutions for several pertinent parameters are provided graphically over specified distributions. The results indicate that the temperature profile intensifies attributable to the increasing thermal radiation parameter. Besides, the increase of Brownian motion parameter pronounces negligible effect on the temperature profile, whereas nanoparticle concentration profile declines. Moreover, increment in the thermophoresis diffusion parameter results in the escalation of the temperature and nanoparticle concentration profiles.

Aim: This study focuses on the numerical analysis of Jeffrey nano-fluid bound with magnetic field in presence of convectively heated boundary. Study Design: Abstract, introduction, Equations formulation, numerical analysis and conclusion Place and Duration of Study: Department of Mathematics and Actuarial Science, Kenyatta University, between 2021-2022 Methodology: This paper discusses the imposed magnetic field on Jeffrey fluid suspended with nanometre-sized particles moving over a vertical sheet with a convectively heated boundary. The partial differential equations are formulated by considering assumptions and the boundary conditions to describe the continuity, momentum, energy and concentration of the fluid. The similarity transformation technique was applied to convert the partial differential equations into first-order linear differential equations which were simulated in Matlab by invoking the Adam’s-Moulton predictor-corrector scheme in ode113. The graphs have been analysed with the effects of Deborah, Dufour-Lewis, Hartman, and Prandtl numbers respectively, solutal stratification, diffusion, thermophoresis, temperature Grashof, mass Grashof, relaxation-retardation parameters on the flow velocity, concentration, temperature, skin friction, heat and mass transfers looked into. Results: While Deborah number increased velocity, it reduced concentration, skin friction and thermal boundary layer at lower numbers hence improved mass and heat transfer. Solutal stratification, Retardation-relaxation parameter and diffusion raised temperature thus heat transfer. Conclusion: Deborah number, solutal stratification, retardation-relaxation parameter and diffusion improves heat and mass transfer.

“…Both relaxation and retardation effects are important in polymer industry since dilute polymer solution is a Jeffrey fluid. (Syazwani Mohd Zokri et al 2017;S. M. Zokri et al 2018) examined the influence of radiation and viscous dissipation on magnetohydrodynamic Jeffrey fluid and Jeffrey nanofluid over a moving plate, a stretching sheet and a horizontal circular cylinder with convective boundary conditions.They found out that the ratio of relaxation to retardation times pronounces the opposite effect to the Deborah number for both velocity and temperature profiles.…”

In this paper, a numerical analysis of boundary layer flow and heat transfer in Jeffrey fluid over a moving flat plate with Newtonian Heating have been presented. The governing partial differential equations were reduced to a transformed ordinary differential equation with the help of similarity transformation. Numerical solutions were obtained for these transformed ordinary differential equation by using the Runge-Kutta-Fehlberg method. The effect on the boundary layer flow and heat transfer behaviours of various parameters such as Deborah number λ2, relaxation time and retardation time ratio λ, Newtonian heating parameter γ, Prandtl number Pr and moving plate velocity parameter ε has been investigated. It is important to mention that the results obtained and reported here are impactful to the researchers working in this field and can be used in the future as a guideline and analysis context.
