Summary: Several phenomena in nature and engineering can be described by nonlinear differential equations, and this study models heat and mass transport in buoyancy-driven nanofluid flow through converging/diverging channels using a non-Newtonian constitutive model. The equations are transformed into a system of nonlinear ordinary differential equations using non-dimensional transformations. The results show that the temperature field is higher at the opening of the flow in the converging channel, and with increasing buoyancy force, the skin friction coefficient decreases while the local Nusselt number increases.

Summary: Tri-hybrid nanoparticles play a crucial role in improving heat and mass transmission in industries with shear rate-dependent viscous fluid. This study investigates the two-dimensional flow of Carreau-ternary hybrid nanoliquid with a magnetic field over a stretching surface. The heat transport mechanism is analyzed through thermal radiation and heat source/sink effects. The research also examines the entropy minimization of the flow and utilizes convective conditions for numerical solution. The results show that increasing the radiation parameter enhances heat transfer rates, while a higher magnetic field parameter decreases entropy generation and liquid velocity.

Summary: This study analyzes a state-of-art multi-generation plant that integrates a scramjet multi-cooling cycle for power, hydrogen, ammonia, and freshwater generation from an energy, exergy, exergoeconomic, and environmental standpoint. The cooling cycle uses the fuel of the scramjet cycle as a coolant and benefits from four-stage compressors to optimize consumed power. Methanol steam reforming procedure is employed to improve the rate of hydrogen production, while a reverse osmosis membrane is integrated into the plant for freshwater provision. Extensive parametric investigation is conducted to consider the impact of input design variables on the implementation criteria of the plant and reduce CO and CO2 emission. The study computes thermodynamic efficiencies, sum unit cost of the products, system emission rate, environment penalty cost rate, and product values as performance criteria for the multi-generation plant, finding that an increase in the hydrogen mole fraction leads to an increase in the emission rate.

Summary: The aim of this work is to study a mathematical model for fractal-fractional tuberculosis and COVID-19 co-infection under the Atangana-Baleanu fractal-fractional operator. The tuberculosis and COVID-19 co-infection model is formulated by considering the tuberculosis recovery individuals, the COVID-19 recovery individuals, and both disease recovery compartment in the proposed model. The existence and uniqueness of the solution in the suggested model are explored using the fixed point approach, and stability analysis related to solve the Ulam-Hyers stability is investigated. This paper is validated through a specific case with a comparative numerical analysis for different values of the fractional and fractal orders, using Lagrange's interpolation polynomial in the numerical scheme.

Summary: The impact of chemical reaction and activation energy is crucial in analyzing the fluid dynamics and thermal properties. The application of fluid flow is widely considered in various fields such as nuclear reactors, automobiles, manufacturing setups, and electronic appliances. In this study, the effects of activation energy and chemical reaction on the magnetohydrodynamic Darcy-Forchheimer squeezed Casson fluid flow through a porous material in a horizontal channel are investigated. Using similarity variables, partial differential equations are converted to ordinary differential equations. The numerical method using MATLAB is employed to solve the problems and obtain data on velocity field, thermal distribution, and concentration distribution. The results indicate that as the plates are brought closer, both the fluid velocity and temperature increase. Moreover, an increase in the Hartmann number leads to a decrease in fluid velocity due to the presence of strong Lorentz forces. The liquid's temperature and concentration increase due to Brownian motion. When both the Darcy-Forchheimer and activation energy parameters are increased, the velocity and concentration decrease.
