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.

人造细菌在具有可变热导率的磁化纳米流体中如何表现：肿瘤减少和癌细胞破坏的应用

目的

该研究旨在确定外部磁场对被数千个磁性磁铁矿纳米粒子包围的细菌的效率。人工细菌在生物细胞中游动的间隙纳米液体具有可变的导热性。考虑二级流体的二维非定常运动。拉伸壁被视为曲面图案。

设计/方法/方法

数学结果是通过切比雪夫伪谱法得到的。

发现

各种控制参数的影响由数字表格和图表描述。事实证明，与磁铁矿/血液相比，纯血液速度曲线更高。从临床疾病中可以看出，危险的肿瘤表现为血流减少。该研究得出结论，血液速度分布随着流体参数值的增加而增加。这意味着药物输送疗法减少了肿瘤体积并有助于消灭恶性肿瘤细胞。血液温度分布随着磁铁矿纳米粒子浓度的增加而增加。因此，通过浸入磁铁矿纳米颗粒可以增强血液的物理性质。此外，目前的结果将热导率清除为温度的可变函数，
