“…The non linear ODE's [14][15][16] along with the end conditions [17] are solved by R-K fehlberg strategy along with shooting method. The shooting method consists of two steps: firstly, the third-order (momentum equation) and second-order (energy and concentration equations) ODE's are transfigured to a first-order ODE system with appropriate boundary conditions and then this BVP system is transformed into an IVP system with some assumptions of missing values at initial boundary.…”

In the current study, we have simultaneously addressed a problem related to the unsteady heat and mass transmission processes in Casson and Williamson nanofluid (i.e., nano sized particles are suspended in considered non-Newtonian fluids). Here both the fluids are considered with electrically conducting property and it is guessed that fluid flow is due to the slippery inclined stretching flat sheet with the appearance of a non-uniform internal heat generation/absorbtion effect. This study also explores the response of viscous dissipation, magnetic strength and Joule heating. Thermophoresis impact along with Brownian motion effect is incorporated and Buongiorno’s model is employed to examine these two aspects. Non-linear equations are made more simpler with the assistance of similarity variables. The numerical solutions are calculated by two different methods, viz., the Runga-Kutta Fehlberg method and bvp5c (along with shooting method) in MATLAB. Graphs are used to express the numerically examined results of concentration, velocity, temperature, Sherwood number, skin friction coefficient and Nusselt number. There is a very good correlation between the current findings and prior published studies in a few specific, constrained situations. The unsteadiness parameter is observed to have a diminishing relationship with the Casson and Williamson fluid momentum boundary layer thickness, thermal profile, and nanoparticle concentration profile. It’s important to remember that a magnetic field raises both the temperature and the nanoparticle concentration within boundary layer.

“…Nuclear reactors, semiconductors, and electronic materials are examples of real-world uses for the heat source/sink phenomenon. Gireesha et al [14] studied the effect of Biot number with an irregular heat source/sink and non-linear thermal radiation of nanofluids in the stretched surface. Khan et al [15] examined the water-based alumina nanofluid implanted in a porous media with buoyancy force that caused a two-dimensional stretched wall jet to transfer heat in fluid flow.…”

Studying waste discharge concentration across a convergent/divergent channel is essential in environmental-related applications. Successful environmental administration must understand the behavior and concentration of waste contaminants released into these channels. Analyzing waste discharge concentrations aids in determining the efficacy of treatment techniques and regulatory controls in lowering pollutant scales. Because of this, the current analysis examines the ternary-based nanofluid flow across convergent/divergent channels, including non-uniform heat source/sink and concentration pollutants. The study also concentrates on understanding the movement and heat transmission characteristics in ternary-based nano-liquid systems with divergent and convergent channels and maximizing the ternary nanofluid flow’s effectiveness. The equations representing the flow, temperature, and concentrations are transformed into a system of ODEs (ordinary differential equations) and are obtained by proper similarity variables. Further, solutions of ODEs are gathered by using the Runge Kutta Fehlberg 4-5 (RKF-45) method and shooting procedure. The significant dimensionless constraints and their impacts are discussed using plots. The results mainly focus on improving local and external pollutant source variation will enhance the concentration for the divergent channel while declining for the convergent channel. Adding a solid fraction of nanoparticles will escalate the surface drag force. These findings may enhance heat management, lessen pollutant dispersion, and enhance the circulation of nanofluid systems.

This study has investigated a Darcy‐Forchheimer thin film flow over an extended horizontal surface with thermal radiation and chemical reaction effects. The governing time‐dependent equations have been non‐dimensionalized using similarity transformations and solved numerically using the fourth‐order Runge‐Kutta method and the shooting technique. The influence of magnetohydrodynamics, non‐uniform heat sourcing, viscous heat radiation, and chemical reactions on temperature, velocity, skin friction, Nusselt, and Sherwood numbers has been examined. Results have shown that porous media, magnetic field, and transient effects decrease the velocity profile, while thermal radiation and variable thermal properties enhance temperature distributions. Findings have indicated that the magnetic field and porosity enhance the skin friction coefficient whereas the heat transfer rate increases with Eckert number and Prandtl number. Rising the chemical reaction parameter from 0.2 to 0.5 rises the mass transfer rate by approximately 9.85%. The thermal analysis of MHD Darcy‐Forchheimer thin film flow in a porous system has been crucial for understanding heat transfer and fluid dynamics in complex environments. It helped in optimizing various engineering processes, such as cooling systems, filtration, and energy conversion, by providing insights into temperature distribution, convective heat transfer, and fluid behavior. This analysis has aided in designing efficient and reliable systems with improved performance and reduced energy consumption.
