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.
