“…They have perceived that the gradients increase as the modified Hartmann number rises. Goud et al 19 inspected the impact of radiation and Joule heating on the magneto flow of nanofluid across an exponentially stretched sheet with a medium of thermal stratified. With increasing values of the Eckert number, the TTBL (thickness of the thermal boundary-layer) is increased as a result of frictional heating.…”

Cooling and heating are two critical processes in the transportation and manufacturing industries. Fluid solutions containing metal nanoparticles have higher thermal conductivity than conventional fluids, allowing for more effective cooling. Thus, the current paper is a comparative exploration of the time-independent buoyancy opposing and heat transfer flow of alumina nanoparticles scattered in water as a regular fluid induced via a vertical cylinder with mutual effect of stagnation-point and radiation. Based on some reasonable assumptions, the model of nonlinear equations is developed and then tackled numerically employing the built-in bvp4c MATLAB solver. The impacts of assorted control parameters on gradients are investigated. The outcomes divulge that the aspect of friction factor and heat transport upsurge by incorporating alumina nanoparticles. The involvement of the radiation parameter shows an increasing tendency in the heat transfer rate, resulting in an enhancement in thermal flow efficacy. In addition, the temperature distribution uplifts due to radiation and curvature parameters. It is discerned that the branch of dual outcomes exists in the opposing flow case. Moreover, for higher values of the nanoparticle volume fraction, the reduced shear stress and the reduced heat transfer rate increased respectively by almost 1.30% and 0.0031% for the solution of the first branch, while nearly 1.24%, and 3.13% for the lower branch solution.

The real-world applications of fluid flow across an exponentially extended sheet are manifold, encompassing crystal formation, paper manufacture, and the cooling of metallic sheets. The primary aim of this study is to conduct a comprehensive theoretical analysis on the behaviour of a hybrid nanofluid flow through an exponentially extended sheet under the influence of quadratic thermal radiation, non-Fourier heat flux and magnetic field. The initially presented equations have been simplified to a set of ODEs, and the bvp4c solver has expertly found solutions to these. Validated the results (of engineering parameters including friction coefficient) obtained using the bar graphs by using Multiple linear regression. It has been noted that a greater magnitude of magnetic field is associated with a temperature enrichment. It is found that higher values of Brinkman number lead to a greater rate of entropy generation. It has been shown that the thermal relaxation parameter (Γ) and magnetic field parameters (M) exert distinct influences on the rate of heat transmission. It is detected that the Nusselt number enhances by 0.700996 (when 0 ≤ Γ ≤ 0.6) and the same declines by 0.14086 (when 0 ≤ M ≤ 3.5). Within the range of 0 ≤ M ≤ 3.5, it is seen that the friction factor exhibits a decline with a notable rate of 1.41843.

The temperature dependent thermophysical fluid properties have numerous aspects in different industries and engineering processes in which heat transmission is based on fluid flow. For such heat transmission processes, heat transmission system is highly fluctuated with variation of viscosity. Thus, the aim of this study is to investigate the transfer of heat in magnetized Carreau fluid with chemical reaction and under influence of thermal radiation over nonlinear stretching/shrinking surface. Additionally, we have incorporated variable heat dependent thermophysical properties to analyze the heat transfer in magnetized Carreau fluid. Set of flow governing non linear PDE’s are obtained using Carreau fluid tensor and boundary layer approximation (BLA) theory. Dimensionless set of ODE’s are obtained using suitable similarity transforms. Shooting method in conjunction with Newton's method have been utilized to solve the problem. It is noted that when stretching $$B\ge 0$$ B ≥ 0 is significant with strictly increasing mass suction $$S$$ S shear stress rate increase with minor levels and sharp increase has been observed in Nusselt number, whereas in shrinking case $$B<0$$ B < 0 shear stress and heat transfer coefficient values are improved raising the value of $$S$$ S mass suction. Further, raising the values of power law index $$n$$ n produce reduced skin friction over stretching surface $$B\ge 0$$ B ≥ 0 while skin friction dramatically enhance in shrinking case $$B<0$$ B < 0 . It is observed that raising the non-linearity $$m$$ m values for stretching or shrinking, skin friction and Nusselt number considerably improved. Moreover, computational outcomes of the study are validated with already published previous results and the results obtained in this study are found in good agreement.
