“…Mathematically, it is the step of the algorithm of the stability analysis. In this study, we relaxed the F ′ (η) → 0 as η → ∞ into F ′′ (0) = 1 (see Harris et al [43]). Utilizing the bvp4c solver, the stability study in this part was carried out.…”

This investigation aims to determine the existence of a dual solution in magne-tohydrodynamic (MHD) mixed convective radiative ternary hybrid nanofluid flow in a permeable Darcy-Forchheimer porous medium over an exponential shrinking surface by considering velocity & thermal slips and suction effects at the surface. The impacts for three types of fluid, namely, the mono nanofluid (Cu/H2O), hybrid nanofluid (Cu-Ag/H2O), and ternary hybrid nanofluid (Cu-Ag-Al2O3/H2O) are analyzed on different flow fields. The current work also addresses estimating entropy production to light on its innovative use in coolant applications. The nonlinear partial differential equations (PDEs) are converted into a set of ordinary differential equations (ODEs) using similarity transformation. Governing higher-order nonlin-ear ODEs are constructed and solved using the bvp4c numerical MATLAB function. Due to the presence of duality in the numerical solutions, the stability of these solutions is performed by locating the lowest eigenvalue. A positive minimum eigenvalue represents the upper stable solution branch, while a negative minimal eigenvalue represents the lower unstable solution branch. The effects of emergent variables on entropy generation and velocity, temperature, skin friction coefficient, and Nusselt number are analyzed graphically and in tabular form. The findings also show that the velocity profile improves when mono nanofluid transitions to hybrid nanofluid. However, it swiftly degrades for a ternary hybrid nanofluid medium for both solution branches. The temperature rises as we transition from mono to hybrid and from hybrid to ternary nanofluid medium. It has been shown that the thermal radiation Preprint submitted to 26 October 2023 parameter significantly influences the fluid’s temperature and the heat transfer rate. In the event of a stable solution, the increment in the Forchheimer number slows the flow of the liquid and is exacerbated by the magnetic field. Thermal radiation also significantly speeds up the creation of entropy. The present optimization method provides a fresh, advantageous perspective on the manufacture of polymer sheets, glass fiber, crude oil, plastic films, heat exchangers, and electronic gadgets. Hence, the obtained results are recommended for developing industrial device setup.

This study aims to examine the magnetized flow of Ag–MgO/water hybrid nanofluid over an extending sheet implanted in Darcy porous medium. Thermal radiations, Joule and viscous dissipations are incorporated into energy equation to account for heat transfer. The convective heat flux boundary condition is imposed at sheet surface. Using non‐similar conversions, governing equations are converted to a system of dimensionless partial differential equations (PDEs). These equations are transformed into ordinary ones by using local non‐similar method. MATLAB's bvp4c function is used to numerically simulate the ordinary differential equations (ODEs). The velocity and thermal profiles for positive variation of essential parameters are illustrated graphically. It was concluded that the velocity profile increases for the rising Darcy number. On the other hand, the temperature profile increased for the positive variation of magnetic number, volume fraction, radiation parameter, Eckert number and Biot number while decreasing for all other parameters. The skin friction coefficient and heat transfer rates are thoroughly investigated and findings are reported through tables. It was found that the magnitude of skin friction coefficient rises with an increase in volume fraction, suction and magnetic parameters while the heat transfer is enhanced by increases in Darcy number, suction parameter, radiation parameter, and Biot number. As per the author's knowledge, no work has previously been published on the current model using the local non‐similarity method. This work may provide insight to researchers interested in thermal systems and solar energy harvesting.

The present research examines the unsteady sensitivity analysis and entropy generation of blood-based silver–titanium dioxide flow in a tilted cylindrical W-shape symmetric stenosis artery. The study considers various factors such as the electric field, joule heating, viscous dissipation, and heat source, while taking into account a two-dimensional pulsatile blood flow and periodic body acceleration. The finite difference method is employed to solve the governing equations due to the highly nonlinear nature of the flow equations, which requires a robust numerical technique. The utilization of the response surface methodology is commonly observed in optimization procedures. Drawing inspiration from drug delivery techniques used in cardiovascular therapies, it has been proposed to infuse blood with a uniform distribution of biocompatible nanoparticles. The figures depict the effects of significant parameters on the flow field, such as the electric field, Hartmann number, nanoparticle volume fraction, body acceleration amplitude, Reynolds number, Grashof number, and thermal radiation, on velocity, temperature (nondimensional), entropy generation, flow rate, resistance to flow, wall shear stress, and Nusselt number. The velocity and temperature profiles improve with higher values of the wall slip parameter. The flow rate profiles increase with an increment in wall velocity but decrease with the Womersley number. Increasing the intensity of radiation and decreasing magnetic fields both result in a decrease in the rate of heat transfer. The blood temperature is higher with the inclusion of hybrid nanoparticles than the unitary nanoparticles. The total entropy generation profiles increase for higher values of the Brickman number and temperature difference parameters. Unitary nanoparticles exhibit a slightly higher total entropy generation than hybrid nanoparticles, particularly when positioned slightly away from the center of the artery. The total entropy production decreases by 17.97% when the thermal radiation is increased from absence to 3. In contrast, increasing the amplitude of body acceleration from 0.5 to 2 results in a significant enhancement of 76.14% in the total entropy production.
