Non-coaxial rotation flow of MHD Casson nanofluid carbon nanotubes past a moving disk with porosity effect

Abstract

In this article, the fluid flow and heat transfer on MHD Casson nanofluid influenced by the non-coaxial rotation of moving disk passing through a porous medium is analyzed. A mixture of single-wall and multi-wall carbon nanotubes in the human Casson blood is used as the nanoparticles. Make use of the Laplace transform technique, the analytical solutions of the temperature and velocity profiles are obtained. The results show that the temperature and velocity profiles increase with the incorporation of CNTs. The nanofluid velocity reduces with a higher magnetic strength, but it is improved with the porosity. The imposition of CNTs has descended both primary and secondary skin friction and amplified the Nusselt number. SWCNTs have provided a greater heat transfer rate and skin friction as compared to MWCNTs. The obtained solution is verified when the present results show an excellent agreement with the published results and numerical values by Gaver-Stehfest algorithm.
