How do artificial bacteria behave in magnetized nanofluid with variable thermal conductivity: application of tumor reduction and cancer cells destruction

Abstract

Purpose The study aims to determine an efficiency of external magnetic field on the bacteria surrounded by thousands of magnetic magnetite nanoparticles. The interstitial nanoliquid in which an artificial bacteria swims in biological cell is utilized with variable thermal conductivity. Two dimensions unsteady motion of second grade fluid are considered. The stretching wall is taken as a curved surface pattern. Design/methodology/approach The mathematical results have been obtained by Chebyshev pseudospectral method. Findings The impact of the various governing parameters is described by numerical tables and diagrams. It is proven that the pure blood velocity curves are higher when compared with the magnetite/blood. It is demonstrated from clinical disease that dangerous tumors show diminished blood flow. This study concludes that the blood velocity profile increases by increasing the values of fluid parameters. This implies that the medication conveyance therapy lessens the tumor volume and helps in annihilating malignancy cells. The blood temperature distribution raises as the magnetite nanoparticles concentration increases. Consequently, the physical properties of the blood can be enhanced by immersing the magnetite nanoparticles. Further, the present outcomes cleared the thermal conductivity as, a variable function of the temperature, has an important role to enhance the heat transfer rate. Originality/value To the best of authors’ knowledge, this study is reported for the first time.

Numerical study of magnetized Powell–Eyring hybrid nanomaterial flow with variable heat transfer in the presence of artificial bacteria: Applications for tumor removal and cancer cell destruction

“…We observed excellent agreement between the results for all profiles. Table 3 shows a comparison between the current and previous results (Elgazery et al, 2022) for skin friction and it was found that both results agreed. Figures 2A-D show comparison between HAM and numerical solutions for the temperature θ(ξ), pressure p(ξ), velocity f ′(ξ), the bacterial density field χ(ξ), nutrient concentration ω(ξ).…”

“… Anantha Kumar et al (2020b) examined the Casson fluid issue in the context of heat radiation-influenced exponentially stretched curved surfaces. Other simulations and investigations of entropy analyses with applications may be seen in Ghachem et al (2018), Elgazery et al (2022) , Rooman et al (2022) , and Maatki (2023) .…”
