Computational Investigation of Stagnation Point Flow of Non-Newtonian Nanofluid on a Rotating Disk with Cattaneo-Christov Heat Flux

Abstract

The exploration of fluid behavior on a rotating disk is crucial because it finds numerous uses across various sectors like engineering, science, and industry. Our present study focuses on examining how heat is transferred around a stagnation point in the flow of Casson nanofluid over a rotating disk. The investigation considers the flow of heat and the distribution of mass within the system, particularly regarding Cattaneo Christov heat flux and chemical reactions. Nonlinear partial differential equations are transformed into ordinary differential equations by the use of similarity transformations, resulting in a reduction in complexity. Subsequently, the Bvp4c method is employed to visualize the graphical outlines and our findings reveal that the fluid's ability to effectively conduct heat is influenced by several parameters. The velocity distribution decline with an increase viscoelastic parameter β, such as the Casson parameter values. Enhancing the Nb parameter improved the temperature distribution but, at the same time, negatively affected the Concentration profile. The outcomes of this research is beneficial in a variety of fields, including transportation, architectural engineering, enhancing oil extraction techniques, and medical applications involving nanofluids.
