A comparative analysis of MoS₂-SiO₂/H₂O hybrid nanofluid and MoS₂-SiO₂-GO/H₂O ternary hybrid nanofluid over an inclined cylinder with heat generation/absorption

Abstract

The present investigation concerns the hydro-thermal characteristics of two different types of hybrid nanofluid flow, namely MoS₂-SiO₂/water hybrid nanofluid and MoS₂-SiO₂-GO/water ternary hybrid nanofluid flow toward an inclined cylinder in the presence of heat generation/absorption and viscous dissipation. Emerging problem occurs as nonlinear partial differential equations (PDEs) included conservation laws of mass, momentum and heat transportation. The relatable problem can be changed into the set of ordinary differential equations (ODEs) using similarity transformations. The Runge-Kutta-Fehlberg (RKF) technique via shooting scheme is adopted to tackle obtained set of ODEs. The influence of significant physical factors on these hybrid nanofluids such as suction/injection, magnetic field, viscous dissipation, and thermal radiation is discussed and depicted by graphs. Also, tabulated results are provided for the skin friction coefficient and rate of heat transfer of both hybrid and ternary hybrid nanofluids. The outcomes describe that the thermal profiles are higher for the ternary hybrid nanofluid than hybrid nanofluid for increasing values of thermal radiation parameter and Eckert number. Also, the velocity profiles of both hybrid nanofluids experience a reduction when higher values of suction/injection parameter are applied. Furthermore, changing the value of the heat generation/absorption parameter from 2.0 to −2.0 leads to 14.74% increment in the heat transfer rate in the hybrid nanofluid, whereas the ternary hybrid nanofluid experience a more significant 28.46% enhancement in the heat transfer rate.
