In the context of advancements in both heat and mass transfer, the current study intends to analyze the impacts of thermal radiation, Soret, and Dufour on the magnetohydrodynamic boundary layer flow through a vertical spinning cone in porous media. The Dufour effect is the energy flux due to the mass concentration gradient with a reciprocal phenomenon, the Soret effect. Energy expression considers the physical aspects of heat generation and absorption. It is expected that the tangential, circumferential, and normal directions will all have velocity components in flow through a porous media. The governing equations are nonlinear partial differential equations that are rearranged into ordinary differential equations via similarity transformation, and then they are numerically solved using the Runge–Kutta method along with a proper shooting strategy. Graphs are used to examine the impacts of many parameters on flow characteristic velocity, temperature, and concentration, including magnetic parameters, porous parameters, Dufour and Soret parameters, chemical reaction parameters, and more. The numerical findings of the gradient of velocity, the Nusselt and Sherwood numbers, and the surface drag force are tabulated and compared with the current result and the one from the literature. The findings are found to be in good agreement. Circumferential and normal velocities are improved visually for greater values of the porosity parameter, but the tangential velocity behavior of the magnetic parameter exhibits the reverse behavior. In addition, the Dufour parameter and chemical reaction both exhibit diminishing behavior when the Soret parameter increases.

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.

Researchers have been paying attention to the utilization of nanofluid since they have disclosed their potentiality as a magnificent working fluid in thermal energy systems. Also, metal-oxide nanoparticles are among the most widely used nanomaterials due to their distinct characteristics such as limited size and high density. Holding such interesting characteristics of oxide-nanoparticles in mind, this research considers heat and mass transport attributes of γ-oxide nanoparticles in chemically reacted kerosene based nanofluid over a vertical cone in the presence of heat generation/absorption. An implicit finite difference method is implemented to obtain the numerical solutions of a constructed mathematical model with the aid of MATLAB software. The effects of numerous parameters on the associated distributions are examined, and their results are illustrated graphically. It is culminated that the velocity and temperature of nanofluid are increased in the presence of heat generation. The thermal conductivity of GO/kerosene is 0.633%, 0.443%, 0.126%, and 0.063% greater than CuO/kerosene, Al2O3/kerosene, TiO2/kerosene, and Fe3O4/kerosene, respectively, at 3% Vol. concentration of nanoparticles. To confirm the authenticity of current research, the acquired results are contrasted with the results of earlier published articles under certain conditions, and an outstanding coexistence is attained.
