Exploring Entropy Minimization in Hybrid Nanofluid Flow Past an Exponentially Stretching Sheet with Significant Quadratic Radiation and Lorentz Forces: A Non-Fourier Heat Flux Analysis

Abstract

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.
