Passive Control of Nanoparticles on MHD Jeffrey Nanofluid past a Convectively Heated Moving Plate with Thermal Radiation

Abstract

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.

Forced Convection of MHD Radiative Jeffrey Nanofluid Over a Moving Plate

“…for different values of Prandtl number when 1 → ∞, = = 2 = 2 = = = = = = = 0. This comparison has clearly certified the authenticity of the numerical results where the present results generated with the help of Maple are in a good agreement with those of Mohamed et al, [21], Bataller [22], Roşca and Pop [25] and Zokri et al, [12]. Figure 2 and 3 are plotted to examine the outcome of magnetic parameter, on the profiles of temperature and concentration.…”

“…Numerical approach via Runge-Kutta Fehlberg method encoded in Maple software is tackled to solve the initial and boundary value problems given in Eq. (8)- (12). The entire investigation is directed to the aftermaths of flow field, temperature, and nanoparticle concentration profiles.…”

“…An experiment conducted by Choi and Eastman [9] has proved that the incorporation of nanoparticles in the non-Newtonian fluids had greatly boosted the fluid thermal capability. To date, many have considered the inclusion of nanoparticles in non-Newtonian fluids, for instance Shah et al, [10] in casson fluid, Waqas et al, [11] in viscoelastic fluid, Zokri et al, [12] in Jeffrey fluid, Zulkifli et al, [13] in micropolar fluid and Tlili et al, [14] in Maxwell fluid. Their studies have highlighted that the random movement of nanoparticles, namely the Brownian motion parameter, helps in enhancing the thermal conductivity.…”

“…The experimental works on nanofluids also have been documented by Ahmadi and Willing [9], Masuda et al [10], Das et al [11] and Pak and Cho [12]. Meanwhile, study via a mathematical approach with various effects and surfaces was reported in work done by Kuznetsov and Nield [13], Mahat et al [14], Zokri et al [15] and Waini et al [16].…”

Aligned MHD Jeffrey Fluid Flow Containing Carbon Nanoparticles over Exponential Stretching Sheet with Viscous Dissipation and Newtonian Heating Effects

“…Ramzan et al, [16] focused on the Jeffrey fluid flow over an inclined stretched cylinder with suspended nanoparticles and investigated the combined impacts of thermal and concentration stratification, thermal radiation, and heat generation/absorption. Meanwhile, Zokri et al, [17] conducted a study to explore the passive control of nanoparticles on MHD Jeffrey nanofluid past a moving plate that was being heated convectively. In line with this, they further their research on Jeffrey fluid flow over a horizontal circular cylinder with suspended nanoparticles and viscous dissipation effect by considering the Buongiorno model [18].…”
