Abstract

Eyring-Powell nanofluids have great potential for use in biomedical engineering to create more effective medical procedures and treatments due to their special properties of fluidity, efficient heat transfer, and interaction with biological systems. This study investigates bioconvection flow and its heat transfer characteristics of the magnetohydrodynamic ternary hybrid nanofluid containing silver, copper, and aluminum nanoparticles with human blood. The forced convection in a porous media, radiation, and viscous dissipation have been considered. The governing equations are reduced to dimensionless partial differential equations and further simplified using the local non-similarity method to obtain ordinary differential equations, which were solved numerically using the BVP4C algorithm. The results indicate that the concentration profiles reduce with inertia coefficients and Schmidt numbers, while radiation parameters increase the surface temperature. A higher Lewis number accelerates thermal diffusion, in contrast to mass diffusion. Fast dissipation of temperature prevents microbial growth and is useful in applications dealing with medicine administration and wound healing. These results support existing research and provide recommendations for further improvement of industrial and biological processes. As the \(M\) rises from \(0.1\) to \(1,\) the Nusselt number declines as follows: for \(Ag\) by around \(4.48\%-2.82\%\), for \(Ag+Cu\) by \(13.57\%, -7.58\%\) and for \(Ag+Cu+Al\) by \(17.21\%-12.53\%\). The Nusselt number increases around \(1.01\%-1.64\%\) as \(\lambda\) rises from \(0.1\) to \(0.3\) for \(Ag\), for \(Ag+Cu\) by the Nusselt number increases by \(6.77\%-13.80\%\) and for \(Ag+Cu+Al\) by \(13.84\%-15.10\%\). The article proposes non-similar transformations for solving complex problems on the movement of ternary nanofluids. This provides insight into medical applications such as drug delivery and diagnostic tools and advances nanofluidic dynamics in healthcare.

三元纳米流体中生物对流MHD流动的辐射耗散效应
由于其特殊的流动性、高效的传热和与生物系统的相互作用,埃灵-鲍威尔纳米流体在生物医学工程中具有巨大的应用潜力,可以创造更有效的医疗程序和治疗。本文研究了含银、铜、铝纳米粒子的磁流体动力学三元混合纳米流体与人体血液的生物对流流动及其换热特性。考虑了多孔介质中的强迫对流、辐射和粘性耗散。将控制方程简化为无量纲偏微分方程,并采用局部非相似法进一步简化得到常微分方程,采用BVP4C算法进行数值求解。结果表明,浓度分布随惯性系数和施密特数的增加而减小,而辐射参数使表面温度升高。与质量扩散相反,较高的路易斯数加速了热扩散。温度的快速耗散防止微生物生长,在处理药物管理和伤口愈合的应用中是有用的。这些结果支持了现有的研究,并为进一步改进工业和生物过程提供了建议。作为 \(M\) 从 \(0.1\) 到 \(1,\) 努塞尔数递减如下 \(Ag\) 按左右 \(4.48\%-2.82\%\),为 \(Ag+Cu\) 通过 \(13.57\%, -7.58\%\) 对于 \(Ag+Cu+Al\) 通过 \(17.21\%-12.53\%\). 努塞尔数大约增加 \(1.01\%-1.64\%\) as \(\lambda\) 从 \(0.1\) 到 \(0.3\) 为了 \(Ag\),为 \(Ag+Cu\) 努塞尔数增加 \(6.77\%-13.80\%\) 对于 \(Ag+Cu+Al\) 通过 \(13.84\%-15.10\%\). 本文提出了求解三元纳米流体运动复杂问题的非相似变换。这提供了深入了解医疗应用,如药物输送和诊断工具,并推进纳米流体动力学在医疗保健。

期刊介绍: Many physicists are turning their attention to domains that were not traditionally part of physics and are applying the sophisticated tools of theoretical, computational and experimental physics to investigate biological processes, systems and materials. The Journal of Biological Physics provides a medium where this growing community of scientists can publish its results and discuss its aims and methods. It welcomes papers which use the tools of physics in an innovative way to study biological problems, as well as research aimed at providing a better understanding of the physical principles underlying biological processes.
