Due to its remarkable thermodynamic development in various engineering sciences, the dispersion of nanostructures in classical base liquids is receiving greater attention from researchers and scientists. In light of the aforementioned inspirations, the suggested research is associated with using a water-based ternary-hybrid nanofluid that contains three unique nanostructures, silicon dioxide, titanium dioxide and aluminum oxide to optimize the heating process in science and engineering. In this situation, the influence of a chemically reactive magneto-hydrodynamics (MHD) Darcy–Forchheimer ternary hybrid composites transport involving nonlinear radiation across an exponentially permeable stretched surface is highlighted with the model's physical initial and boundary constraints. The simulation of the heat expression also includes the impacts of nonlinear thermal radiations, energy supply, energy dissipation and magnetic force. Furthermore, the interpretation of Buongiorno's theory involves spontaneous and thermophoresis diffusions. Entropy analysis is explained using the second law of thermodynamics. We converted the model framework for fluid movement, energy and mass transfer (together with ternary hybrid nanofluid characteristics) into self-similar nondimensional differential equations, that were then further analytically evaluated by using the homotopy asymptotic method (HAM) technique via Mathematica software. The acquired results are illustrated numerically and graphically to study the behavior of fluid flow, heat, concentration distribution, drag force, rate of heat and mass transfer for various emergent components to gain scientific comprehension. With the growing values of magnetic, porosity and Forchheimer number, the nature of the velocity profile goes down.

Tri-hybrid nano-particles in shear rate-dependent viscous fluid are essential for improving heat and mass transmission in many industries. The current study explores the two-dimensional flow of the Carreau-ternary hybrid nanoliquid with a magnetic field over the stretching surface. The heat transport mechanism is deliberated through the applications of thermal radiation and heat source/sink effects. The entropy minimization of the flow of Carreau ternary hybrid nanofluid has also been scrutinized. Further, the concepts of convective conditions are employed for the numerical solution of the existing model. In the present flow analysis, silver (Ag), Molybdenum disulfide (MoS2), and multi-wall carbon nanotube (MWCNT) nanoparticles are studied. Carboxymethyl cellulose (CMC-water) is used as a base liquid. The well-established numerical collocation finite difference scheme and three-stage Lobatto III as the built-in function of the bvp4c solver via MATLAB have been used to solve the system of equations in the form of concentration, energy, and momentum. Numerous features, such as flow speed, temperature, drag friction, and Nusselt number, are described in figures and tables. From the existing model, some key outcomes are that the rising values of the radiation parameter increased the heat transfer rates. Further, it is dissected that the greater importance of the magnetic field parameter declined the entropy generation and velocity of the liquid.

This study explores the impact of thermal radiation and viscous dissipation on the stagnation point flow of a copper–water nanofluid across a convective stretching/shrinking cylinder. The copper suspension in the base fluid water enables the fluid to conduct more heat by increasing its thermal conductivity. The mathematical model that governs the flow of Cu-H2O nanofluid is formulated by the system of partial differential equations (PDEs) which are then subjected to transformation by introducing suitable similarity variables so the system is transformed to the Ordinary Differential Equations (ODEs). These equations have been solved numerically via the bvp4c package in MATLAB. The outcomes have been signified graphically in the form of heat transfer rate, temperature, skin friction and velocity which are dependent on the concerning flow parameters. For each of these result, dual solutions have been produced which are conditional on the shrinking of cylinder. These results declare that the skin friction increases for the shrinking cylinder and decreases for the stretching cylinder whereas an opposite trend is seen for the rate of heat transfer. Similarly, heat transfer is found to be decreasing for the increase in both Biot and Eckert number. Meanwhile, the existence of greater values of curvature parameter causes to enhance both first and second solution of velocity as well as the temperature is augmenting with the increase in Eckert number and volume fraction of nano particles.
