Heat and Mass Transfer of CNTs Blood-based Casson Nanoliquids MHD Flow over a Rotating Stretchable Disk with Magnetic Field and Heat Source

Abstract

Carbon nanotubes (CNTs) are being used in nanomedicine as drug delivery systems, particularly for the medical therapy of cancer. The CNTs are initially infused into the blood, which then travels to the tumour via waves generated by the artery walls in the presence of an outside influence, like a magnetic field. This article analyses the study of heat and mass transmission in a blood-based Casson nanoliquid MHD flow using single-wall (SW) and multi-wall (MW) carbon nanotubes (CNTs) on a rotating disc with a heat source and magnetic field effects. The suspension of both kinds of carbon nanotubes is accomplished using Casson blood. The spinning and extending of the disc cause the flow to be formed. The controlling nonlinear PDEs are transformed into nonlinear ODEs, and ODEs are resolved using the Runge-Kutta fourth-order approach in MATLAB's bvp4c package. By means of graphical representation, the effects of different model restrictions are highlighted for the following parameters: momentum, energy transport, concentration, microorganism profiles, drag coefficient, heat and mass transport rates, and motile density number. This study demonstrates that the fluid momentum of a single-walled CNTs-blood Casson nanofluid is relatively less impacted and that the heat profile of this nanofluid is more dominant than that of a multi-walled CNTs-blood nanoliquid. The outcomes further show that with higher levels of the volume fraction of nanoparticles, the friction factor and rate of heat transport are improved.
