Flow of Elastoviscous Nanofluid Through an Elongating Surface With Dissipative Heat: A Confluent Hypergeometric Solution

ABSTRACT Thermal energy transport likely through polymer extrusion, cooling of metallic plates, and chemical processing equipment relating to the flow of viscoelastic nanofluid has a greater role in engineering because of its elastic characteristics. The current investigation deals with thermally dissipative flow of viscoelastic nanofluid comprised Fe 3 O 4 nanoparticles in water through an intensifying surface embedding within a porous medium. The illustration of radiating heat along with heat generation reflects the real‐world thermal gradient properties used in energy‐intensive industrial processes. The reduction of the model into a system of ordinary equations is intended for the utilization of similarity rules. The resulting system is analytically solved utilizing the confluent hypergeometric function approach, i.e., Kummer's function. The impact of key factors controlling the flow phenomena is systematically analyzed, and the validation of the result in a particular case of pure fluid is discussed with regard to an earlier investigation. In important aspects, it reveals that the fluid momentum is significantly affected by the non‐Newtonian viscoelastic parameter, where the radiative heat with heat generation augments the heat transport phenomena.
