Soret and Dufour influences on forced convection of Cross radiative nanofluid flowing via a thin movable needle

Abstract

The main feature of the current investigation is to analyze the magnetohydrodynamic mixed convection flow of Cross fluid. Flow is due to a movable thin needle with Soret and Dufour effect. Heat generation/absorption and nonlinear heat radiation are used in the energy equation. Characteristics of the chemical reaction and thermal activation are given special attention. Appropriate variables are introduced for the transformation of partial differential equations to ordinary differential equations. With the assistance of Runge–Kutta Fehlberg's fourth- fifth-order method with the shooting technique, we determined the prominent result numerically. The prominent examined parameters range is velocity and temperature ratios, heat generation, Dufour, Hartmann, Schmidt numbers ($$0.1\le{{\lambda}},{{{\theta}}}_{{{w}}},{{Q}},{{{D}}}_{{{u}}},\boldsymbol{ }{{M}},{{S}}{{c}}\le 0.7$$ 0.1 ≤ λ , θ w , Q , D u , M , S c ≤ 0.7 ), needle thickness ($$0\le {{a}}\le 15$$ 0 ≤ a ≤ 15 ), radiative parameter ($$5\le {{R}}{{d}}\le 8$$ 5 ≤ R d ≤ 8 ), and Weissenberg number ($$0.01\le {{W}}{{e}}\le 0.09$$ 0.01 ≤ W e ≤ 0.09 ), respectively. Graphs for velocity, thermal, concentration, Skin friction coefficient, and heat and mass transport rates are displayed and analyzed for physical parameters. A similar observation of mixed convection and needle thickness parameter is seen on the velocity field. Temperature and heat transfer rate are reverse behavior in the frame of the Dufour effect. Moreover, an enhancement in chemical reaction shows decay to the concentration field.

Comprehensive examination of radiative electromagnetic flowing of nanofluids with viscous dissipation effect over a vertical accelerated plate

“…Finally, further research can be considered by incorporating different nanoparticles in the fluid to study their thermal enhancement under a vertical plate for hybrid and ternary hybrid nanofluids. The G-FEM could be a potential utilization for future science and technology challenges [44][45][46][47][48][49][50][51][52][53][54][55][56][57][58] .…”

Significance of Dufour and Soret aspects on dynamics of water based ternary hybrid nanofluid flow in a 3D computational domain

“…Kabeir et al 40 worked on heat and mass transfer in magnetized flow of mixed convective stagnant power law non-Newtonian fluid with diffusion aspects. Dufour and Soret impacts on magnetohydrodynamics mixed convective fluid flow of cross fluid was examined by Rehman et al 41 . Shahnaz et al 42 made the mathematical modeling for 2-D double diffusive flow of MHD Maxwell fluid.…”

“…In the future work, it might be applicable by considering cylindrical surface with bio-convection radiative flow [13] , Darcy-Forchheimer flow [56] and non linear thermal radiation with hybrid nanofluid [25] . Besides, it might be extended by including the impact of Buoyancy [26] , [57] .…”
