Hydrothermal behavior and irreversibility analysis of Bödewadt flow of radiative and dissipative ternary composite nanomaterial due to a stretched rotating disk

Bödewadt flow and heat transfer characteristics of radiative and dissipative ternary composite nanomaterial over a stretched rotating disk is investigated. Flow is subjected to second order boundary slip. Entropy optimization due to radially stretched flow of ternary composite nanomaterial is executed. The main purpose of this novel study is to investigate the improvements in the heat transfer performance and flow behavior of the present system through the use of ternary composite nanomaterial compared to the thermal performance of hybrid and mono nanofluids subject to second order slip condition. The ternary composite/hybrid nanomaterial is a mixture of water as base fluid and Al₂O₃, Graphene and MWCNT as nanoparticles. The numerical solution is obtained by using bvp4c method through MATLAB. The most important physical conclusion of the present investigation is that introduction of ternary composite nanofluid to the Bödewadt flow over a stretched rotating disk gives rise to. controlled motion subject to slip condition, reduces surface viscous drag effectively and ameliorates heat transfer rate thereby imparting significant cooling compared to binary hybrid nanofluid and mono nanofluid.
