Comparative flow and thermal transfer aspects of Casson Hybrid Nanofluid and Williamson Hybrid Nanofluid dispersed in the mixture of water and ethylene glycol with variable thermal conductivity

Comparative study of the flow of Casson Hybrid Nanofluid and Williamson Hybrid Nanofluid

Abstract

This manuscript is prepared to deal with the comparative fluid flow and thermal transportation aspects of Casson Hybrid Nanofluid and Williamson Hybrid Nanofluid dispersed in the mixture of water and 30%  C₂H₆O₂  over an exponentially stretching cylinder. The suction effect, MHD effect, and the impact of variable thermal conductivity are also incorporated into the concurrent flow model. The spherical-shaped  Ag and MoS₂ are used as nanoparticles. It has been established that the shear stress rate and Nusselt number are lesser for Williamson hybrid nanofluid as compared to hybrid nanofluid, but the opposite is the trend for Casson Hybrid Nanofluid. Also, the skin friction coefficient is very high in Casson Hybrid Nanofluid in comparison to Williamson Hybrid Nanofluid. In addition to this, the thermal transfer rate is found to be enhanced by up to more than 4% in Casson Hybrid Nanofluid as compared to Williamson Hybrid Nanofluid for all the parameters.
