“…Li et al [23] presented the potential effects of a spinning cone on the convective transport of a viscous nanofluid in their groundbreaking study. The intricate relationship between the transfer of mass and heat around a cone that is rotating vertically has been better understood thanks to Saleem's meticulous research, which is referenced in [24] When exposed to a magnetic field, a nanofluid within a spinning cone exhibited unpredictable behaviour, as demonstrated by Nadeem and Saleem [25].…”

This study seeks to investigate the phenomenon of heat transfer in a rotating cone submerged in a non-Newtonian Carreau fluid. The Carreau fluid is highly regarded for its shear-thinning behavior and its wide range of practical applications. Using a shooting method for numerical simulation and an Artificial Neural Network algorithm (ANN), specifically the back-propagation Levenberg-Marquardt Scheme (BLMS), we thoroughly analyze the intricate interplay between buoyancy and centrifugal forces through a rigorous analytical approach. The findings of our study make valuable contributions to the understanding of the fundamental significance of centrifugal forces and buoyancy in the domains of fluid dynamics and heat transfer. An in-depth analysis is conducted on the convective heat transfer process, considering crucial factors like the Nusselt number, Reynolds number, Grashof number, fluid velocity, and cone rotation. This work emphasizes the importance of further research into fluid flow and heat transfer dynamics. It specifically focuses on the interaction between various parameters, including thermal radiation, Thermophoresis, Brownian motion, viscous dissipation, and non-Newtonian complexity. This thorough investigation has the potential to significantly enhance precision and efficiency in various manufacturing applications.

“…Another study on the flow across a cone/wedge for an Oldroyd-B fluid was considered in the study conducted by Reddy et al [10]. Further, Reddy et al [11] estimated non-linear thermal radiative nanofluid steady flow over a rotating cone and Saleem [12] accounted for third-grade fluid flow properties for a rotating cone. A study on water-based nanofluid through a conical surface with single and multi-wall carbon nanotubes was considered by Shah et al [13].…”

The objective of the present work is to examine the characteristics of unsteady incompressible magnetohydrodynamic fluid flow around a permeable rotating vertical cone. The effects of thermal radiation, viscous dissipation, and the Soret and Dufour effects are investigated in the analysis of heat and mass transfer. The viscosity of the fluid is considered inversely proportional to the temperature, and the thermal conductivity of the fluid is considered directly proportional to the temper-ature. The governing equations are converted into ordinary differential equations using suitable similarity transformations, which are then solved numerically using bvp4c from MATLAB. Results obtained in this study are in excellent correlation with previously conducted studies. The results demonstrate that the Dufour and Soret effects subsequently reduce the heat transit rate (by –3.3%) and mass transit rate (by –1.2%) of the system. It is also detected that fluids with higher viscosity tend to increase tangential skin friction (+8.9%) and azimuthal skin friction (+8.3%). The heat transit rate of the system is found to be more efficient for fluids with higher viscosity and lower thermal conductivity and Eckert numbers. Further-more, the thickness of the momentum, thermal, and concentration boundary layers significantly reduces while the heat and mass transit rates (+17.8% and +18.3%, respectively) of the system become more efficient for greater values of the un-steadiness parameter.

“…The essential rules governing temperature regulation in a dynamic hybrid nanofluid were uncovered by Gul et al [22] in their study. A fuller comprehension of the complex interaction between mass and heat transmission surrounding a vertically spinning cone can be credited to Saleem [23] for diligent research. A hybrid system was used as the study's theoretical framework as Hussain et al [24] examined the complex phenomenon of mixed convection in a nanofluid.…”

Heat transport in a dynamically rotating cone immersed in a Carreau fluid is the subject of this investigation. The fluid is a non-Newtonian, admired for its shear-thinning characteristics and utilized extensively in numerous industrial domains. The study investigates the interplay between buoyancy and centrifugal forces within the analytical framework. In order to find a solution, we will use numerical simulation with an ANN algorithm, namely the back-propagation Levenberg-Marquardt Scheme (BLMS), in conjunction with the Shooting mechanism. The enormous influence of centrifugation and buoyancy on the complex fluid dynamics and heat exchange processes is clearly proved by the results. Some important parameters that govern the convective heat transport process are the Nusselt number, the Reynolds number, the Grashof number, and the fluid and cone rotational velocities. The study confirms the need of taking non-Newtonian complexities and viscous dissipation into account when studying heat transfer dynamics and fluid flow, which could lead to more accurate predictions and better efficiency in a variety of industrial processes.
