Analytical study explores double-diffusive nanofluid flow in arterial channels, indicating improved heat transfer with increased nanotube concentration.
Key Points
This research aims to analyze the flow of carbon nanotubes in a Casson blood model within porous arterial channels.
Modeled blood as a Casson nanofluid with carbon nanotubes suspended in it.
Applied double diffusion principles for heat and mass transfer in a porous medium.
Governed the flow dynamics using partial differential equations with defined boundary conditions.
Derived dimensionless equations and obtained analytical solutions using the Laplace transform method.
Validated results using numerical methods like the Gaver–Stehfest algorithm.
Increasing the CNT volume fraction enhances velocity and temperature profiles.
A 6% CNT volume fraction improves heat transfer by 23.22% (SWCNTs) and 21.82% (MWCNTs) while reducing mass transfer by 4.08%.
The highest magnetic field decreases velocity by 8.5%, while higher porosity increases it by 5%.
SWCNTs show higher Nusselt numbers (1–2.3%) and lower shear stress (0.5–0.7%) compared to MWCNTs due to better thermal conductivity.
