Magneto-Hybrid Nanofluids Flow via Mixed Convection past a Radiative Circular Cylinder

Abstract

The goal of the current analysis is to scrutinize the magneto-mixed convective flow of aqueous-based hybrid-nanofluid comprising Alumina and Copper nanoparticles across a horizontal circular cylinder with convective boundary condition. The energy equation is modelled by interpolating the non-linear radiation phenomenon with the assisting and opposing flows. The original equations describing the magneto-hybrid nanofluid motion and energy are converted into non-dimensional equations and solved numerically using a new hybrid linearization-Chebyshev spectral method (HLCSM). HLCSM is a high order spectral semi-analytical numerical method that results in an analytical solution in η-direction and thereby the solution is valid in overall the η-domain, not only at the grid points. The impacts of diverse parameters on the allied apportionment are inspected, and the fallouts are described graphically in the investigation. The physical quantities of interest containing the drag coefficient and the heat transfer rate are predestined versus fundamental parameters, and their outcomes are elucidated. It is witnessed that both drag coefficient and Nusselt number have greater magnitude for Cu-water followed by hybrid nanofluid and Al2O3-water. Moreover, the value of the drag coefficient declines versus the enlarged solid volume fraction. To emphasize the originality of the current analysis, the outcomes are compared with quoted works, and excellent accord is achieved in this consideration.

Impacts of Viscous Dissipation and Brownian motion on Jeffrey Nanofluid Flow over an Unsteady Stretching Surface with Thermophoresis

“…The partial differential equations (PDE) system ( 7)-( 10) has a multi-scale solution behavior over an infinite interval where the solution varies quickly over the boundary layer and away from this layer the solution varies slowly and behaves regularly and that is according to the time constants of the solution components. Moreover, the PDE system (7)-( 10) is very sensitive to the initial conditions due to the singularity associated with the highest derivative-term in the system and hence more accurate and efficient adaptive methods are required for solving this class of PDE systems [5,[27][28][29][30][31][32]. System ( 7)-( 10) is converted into a first-order PDE system and discretized using a fourth-order finite difference method in η-orientation and a two-point backward finite difference method [28] in τ-orientation.…”

“…Jakeer et al [30] discussed magneto Cu-Al 2 O 3 /water hybrid nanofluid flow in a non-Darcy porous square cavity and found that the Cu-Al2O3/water nanofluid provides a higher heat transfer. MHD convective flow of water-based hybrid-nanofluid containing Alumina and Copper nanoparticles through a horizontal circular cylinder was studied by Zahar et al [31]. Futhermore, Ghalambaz et al [32] investigated nano encapsulated phase change material in a glass ball porous medium, where the nanoparticles comprise of PCM core (nonadecane) and a shell (polyurethane).…”

On some wavelet solutions of singular differential equations arising in the modeling of chemical and biochemical phenomena

“…The MHD flow has a wide range of applications in the fields of chemistry and biology, for instance, the fabrication in cancer tumor therapy resulting hypothermia, decreasing bleeding in the state of acute injuries, magnetic resonance visualizing, and various other diagnostic experiments [3]. Magnetohybrid nanofluids flow via mixed convection past a radiative circular cylinder was studied in [4]. The EHD flow of a fluid is modeled by a set of partial differential equations, which can be reduced to an ordinary differential equation as in [16], and results in the following Emden-Fowler type of equation:…”
