Natural Convection Flow of Casson Fluid with Carbon Nanotubes Past an Accelerated Disk

Abstract

In this study, the impact of heat transfer on free convective Casson nanofluid flow induced by an accelerated disk is analyzed. The study of non-Newtonian Casson nanofluid that is suspended by single wall carbon nanotubes (SWCNTs) and multi wall carbon nanotubes (MWCNTs) has a vital role in human blood flows. The problem is governed by governing momentum and energy equations that come along with appropriate conditions for initial and accelerated boundary. The dimensionless form of the governing equation is then derived by applying the suitable dimensionless variables. An exact solution of temperature and velocity fields is obtained by utilizing Laplace transform technique. The impacts of pertinent parameters such as Casson parameter, Grashof number, nanoparticle volume fraction and time on both profiles are discussed and illustrated graphically. It is found that both temperature and velocity distributions satisfyingly meet all the initial and boundary conditions. The addition of CNTs particles leads to an increase in both temperature and velocity profiles, and SWCNTs possess a higher magnitude of temperature due to its outstanding thermal conductivity when compared to SWCNTs.

The Newtonian heating effect on MHD free convective boundary layer flow of magnetic nanofluids past a moving inclined plate

“…The study found that the Grashof number has improved the velocity field and lowered the momentum boundary layer thickness. The study on free convection was rapidly established by considering the different problems and situations by Hamdan et al (2020) and Mohamad et al (2022). They found that the Grashof number has a significant impact on the velocity and momentum boundary layer thickness.…”

Impact of Nanoparticles Shapes on Magnetohydrodynamic Flow and Heat Transfer of Casson Hybrid Nanofluids over a Moving Inclined Plate

“…Aman et al, [17] investigated the presence of MHD on the unsteady flow and founds that an increases values Casson parameter, the velocity is increase while velocity is decrease when magnetic parameter is increases. There have been several investigations into the MHD effect in different problems and found that MHD effect have an important impact on the boundary layer flow [18][19][20][21][22][23][24][25][26][27][28][29].…”
