Heat transfer enhancement of forced convection magnetized cross model ternary hybrid nanofluid flow over a stretching cylinder: Non-similar analysis

Abstract

Nanofluids have exhibited substantial promise in amplifying thermal efficiency across a spectrum of industrial domains. Concurrently, the study of flow dynamics through a stretching cylinder assumes paramount importance within contemporary construction paradigms, spanning the realms of polymer processing, metal sheet manipulation, biomechanics, and advanced medical applications. Bolstering these pragmatic contexts, the ongoing inquiry is focused on scrutinizing the reverberations of thermal radiation upon the laminar Cross model flow, ensconced within a magnetized ternary hybrid nanofluid. This, in turn, reverberates through the intricate tapestry of heat transfer phenomena. The fluidic flux is orchestrated by a stratified stretching cylinder, ensconced within the labyrinthine confines of a porous medium. The research intricately highlights pivotal attributes of the fluid, encompassing its intricately temperature-tethered thermal conductivity and its hinging upon the nuanced orchestra of temperature distribution. Furthermore, it cast an illuminating spotlight on the incipient cascades of ohmic heating, significantly sculpting the heat exchange contours within fluidic streams. The controlling equations are turned into dimensionless partial differential equations via non-similarity transformations. subsequently, the local non-similarity approach is utilized to treat the dimensionless PDEs as ODEs, and bvp4c MATLAB tools are used to effectively solve them. Subsequently, graphical representations are provided to illustrate the changes in the velocity profile and temperature profile resulting from variations in parameters such as the Weissenberg number, porous parameter, thermal conductivity parameter, Magnetic parameter, and Eckert number. Under the given physical circumstances, the Nusselt number representing the temperature gradient and the local skin friction coefficient were determined. Notably, the heat transport mechanism is significantly affected by both thermal radiation and ohmic heating. Furthermore, the warming effects inside the thermal boundary layer are especially important for the Darcy parameter and magnetic parameter, which makes them of particular relevance in heat transfer issues. In the end, the results show how successful the suggested numerical technique is since it offers a thorough depiction of the flow and heat transfer processes.
