Summary: The paper investigates the Arrhenius-driven chemical reaction in an upstanding micro-channel under an imposed transverse magnetic field with fully developed constant free convection flow. The temperature and velocity equations are solved using the homotopy perturbation method, and the effects of various parameters on the flow behaviors are explored. The findings are represented in mesh grid graphs, showing that increasing the rarefaction parameters and chemical reaction results in an increase in fluid velocity and volume flow, while increasing the Hartman number leads to flow retardation. The numerical comparison with previous results shows excellent agreement when the chemical reactant parameter is ignored.

Summary: In this study, we investigated the influence of entropy generation on Maxwell hybrid nanofluid over a cylinder in the presence of non-linear thermal radiation and Cattaneo-Christov heat flux. We compared the solutions obtained using numerical method (NM) and homotopy perturbation method (HPM) and found that HPM provided more accurate and reliable outcomes. The results showed that higher magnetic parameter led to lower fluid velocity, higher heat generation parameter improved temperature profiles, and Darcy-Forchheimer number and temperature time relaxation parameter decreased Nusselt number. This type of flow problems is important for improving blood flow in blood vessels.

Summary: The study focuses on the stability test of electrical magneto hydrodynamic stagnation point flow of hybrid nanofluids with entropy generation, considering velocity and thermal slips over a porous slendering stretchable sheet. Mathematical modelling of Ag-Cu/water hybrid nanofluid is carried out to evaluate the heat transfer proficiency of airplane wings, taking into account effects like viscous dissipation and solar-based thermal radiation. By using self-similarity transformations and bvp4c in MATLAB software, the system of fluid transport equations is solved in the form of ordinary differential equations, and the achieved outcomes include skin friction, Nusselt number, velocity, temperature, Bejan number, entropy generation, and streamlines. The effects of different physical parameters on flow and heat transfer are demonstrated through graphs. It is observed that the first solution exhibits better stability, and the wall thickness variable has contrasting impacts on the velocity profile of the hybrid nanofluid for the two solutions. Higher thermal radiation parameter leads to increased temperatures in both solutions, and the rate of heat transfer is enhanced with higher electric field values in the first solution.

Summary: The research aims to control fluid flow in a vertical microtube by creating a pressure gradient through heat transfer analysis. The motion of the membrane generates pressure, regulated by buoyancy forces. Wall deformation and membrane kinematics result in fluid movement. Analytical solutions were derived using dimensional analysis and lubrication technique, and simulations were conducted using MATLAB software. The impact of parameters on various flow properties and variables was visually demonstrated. Results showed that the volumetric flow rate increased with Debye length progression, while it had the opposite effect with Helmholtz-Smoluchowski. Streamlines did not vary significantly during contraction but showed extreme contour outlines during expansion in Helmholtz-Smoluchowski.

Summary: The study investigates the impact of double diffusion, activation energy, Brownian motion, thermal radiation, thermophoresis, viscous dissipation, magnetic field, and Joule heating on bioconvection of a tangent hyperbolic nanofluid flow over a vertical stretching porous surface containing microbe. The fluid transport equations are solved using the finite difference method and the effects of key parameters on the fluid's transport properties are depicted in graphs and tables. It is observed that higher dimensionless activation energy leads to a decrease in mass transfer rate at the stretched nanomaterial sheet, and the concentration of the nanofluid near the sheet decreases with an increase in the porosity parameter value, but the opposite behavior is observed far from the sheet.

Summary: The objective of this article is to study entropy generation in EMHD thermal transports of hybrid nanofluid. Non-Newtonian fluids are employed in the physical model, along with blood and hybridized gold (Au) and silver (Ag) to form a diluted and homogeneous combination. The non-linear PDE system is transformed into an ordinary differential system using self-similarity variables and the homotopy perturbation technique. Visual representations are used to illustrate the effects of various factors. The results closely align with existing literature, showing that the radial and azimuthal velocity profiles decrease when inclined to the parameters of magnetic, Casson, and Williamson fluids, contradicting the increase in electric field inputs. Entropy production increases for magnetic fields while the Bejan number decreases. These predictions are relevant to targeted nanoparticle drug delivery in hematology.
