Radiative and porosity effects of trihybrid Casson nanofluids with Bödewadt flow and inconstant heat source by Yamada-Ota and Xue models

Abstract

Researchers across the world have tried to explore the impact of various hybrid nanoparticles in the case of fluid moving over a disk with the inclusion of various effects to investigate heat and made transfer analyses of fluid. The present article is designed to scrutinize the influence of Diathermic oil (DO) with the inclusion of tri-hybrid nanoparticles by adopting a tri-hybrid Yamada-Ota and Xue nanofluid model. The article is novel in the sense that the extension in Yamada-Ota and Xue nanofluid models in the case of tri-hybrid nanoparticles has never studied before in the existing literature. Diathermic oil (DO)is a great quality mineral oilthat has been refined to assure long-term service due to its outstanding resistance to thermal cracking and chemical oxidation; also, its high specific heat and thermal conductingoffer fast heat loss. Our goal in this work is to compare the concert of the Yamada-Ota and Xue representations for a nanofluid movement between two revolving disks in a spongy medium in light of these astonishing physiognomies. The entire scenario is thought out with different traits. Using the Keller box approach, the governing system's numerical solution is achieved. The feature consequences of ascending constraints solid nanoparticles capacity fraction (0.005≤ϕ=ϕ1+ϕ2+ϕ3≤0.15), heat ratio θw, fluid parameter β, porosity parameter M, temperature generating and sink having varieties A∗, and B∗, radiative parameter Rd, and Eckert number Ec between 0.1 and 2, versus connected outlines are examined. When the variable viscosity parameter (for gases) is positive, the axial velocity decreases; however, when the varying viscidness parameter is negative, the rapidity distribution increases (liquids).
