Entropy-optimized melting heat transport of Casson-Williamson hybrid nanofluid with blood-mediated nanoparticles over a rotating disk

The objective of the current article is to probe entropy generation in EMHD thermal transports of hybrid nanofluid which has indeed been enhanced by better thermal transfer to handle growing heat density of tiny and other technological operations. Non-Newtonian fluids like Casson and Williamson are encrypted for this present physical model and also in the blood, gold (Au) and silver (Ag) are hybridized to form an extremely diluted, homogeneous combination. The non-linear PDE system of equations are synthesized into an ordinary differential system via appropriate self-similarity variables, which are then computed by utilizing the homotopy perturbation technique. Visual representations are used to demonstrate the effects of various factors. With a few exceptions, the model's study results are pretty close to those found in the literature. For various profiles, with the influence of active parameters, the results are displayed graphically. This shows that when the parameters of magnetic, Casson and Williamson fluids are inclined, the radial and azimuthal velocity profiles decrease, sharply it attains contradiction phenomena to the increasing electric field inputs. Entropy production increases for magnetic fields and the Bejan number exhibits declination. The predictions are pertinent to the delivery of targeted nanoparticle drugs in hematology.

Automated summary

The objective of this article is to study entropy generation in EMHD thermal transports of hybrid nanofluid. Non-Newtonian fluids are employed in the physical model, along with blood and hybridized gold (Au) and silver (Ag) to form a diluted and homogeneous combination. The non-linear PDE system is transformed into an ordinary differential system using self-similarity variables and the homotopy perturbation technique. Visual representations are used to illustrate the effects of various factors. The results closely align with existing literature, showing that the radial and azimuthal velocity profiles decrease when inclined to the parameters of magnetic, Casson, and Williamson fluids, contradicting the increase in electric field inputs. Entropy production increases for magnetic fields while the Bejan number decreases. These predictions are relevant to targeted nanoparticle drug delivery in hematology.
