Abstract:
The current study presents a bioconvective model to investigate the dynamics of water conveying single-wall carbon nanotubes (SWCNTs) and magnetite nanoparticles on the stagnation point flow along a stretching sheet subject to chemical reaction, viscous dissipation, induced magnetic field, and stratification effects. With applications ranging from biomedical imaging, hyperthermia, targeted drug delivery, and cancer therapy, the present study provides a theoretical perspective that is beneficial in biomedical engineering. Relevant similarity formulas are effectuated in converting the governing equations into a system of ODEs and are further treated numerically using the Runge-Kutta-Fehlberg method with the shooting technique. Illustrations on the effect of temperature, microorganisms, concentration, and velocity profiles due to the varying parameter values are achieved with the aid of graphs. It is observed that augmenting volume fraction of single-wall carbon nanotube and magnetite nanoparticles exhibit a constructive effect on temperature profile, which helps in killing cancerous cells. Further, the simultaneous impact of effectual parameters on surface drag, heat transfer rate, mass transfer rate, and microorganism density number is studied using graphs. It is seen that augmenting chemical reaction parameter tends to elevate the mass transfer rate and the microorganism density number.
