Biological structural study for the blood casson fluid flow in catheterized diverging tapered stenosed arteries with emerging shaped nanoparticles: application in drug delivery
The current research focuses on investigating the influence of magnetic forces and differently shaped nanoparticles within diverging tapering arteries afflicted with stenoses, utilizing a blood flow model. A notable aspect of this study is the exploration of metallic nanoparticles of various shapes within a water-based fluid medium, a research area that remains largely unexplored. To simulate blood flow dynamics, a radially symmetric yet axially non-symmetric stenosis configuration is employed, providing insights into the complex flow patterns within diseased arteries. A significant contribution of our research lies in the analysis of the symmetrical distribution of wall shearing stresses and their correlation with resistive impedance. Moreover, we investigate the progressive rise of these quantities in tandem with stenosis severity. Through numerical simulations, we evaluate several flow parameters, including velocity, temperature, resistance impedance, boundary shear stress, and shearing stress at the stenosis throat. These assessments provide a comprehensive understanding of the multifaceted effects of nanoparticle shape and magnetic forces on blood flow characteristics within tapered arteries. Furthermore, our study explores the graphical representation of various flow quantities across a spectrum of relevant parameters for Cu-blood systems. By examining different types of tapered arteries, particularly diverging tapering configurations, we gain insights into the intricate interplay between arterial geometry, fluid rheology, and nanoparticle behavior.
期刊介绍:
Microfluidics and Nanofluidics is an international peer-reviewed journal that aims to publish papers in all aspects of microfluidics, nanofluidics and lab-on-a-chip science and technology. The objectives of the journal are to (1) provide an overview of the current state of the research and development in microfluidics, nanofluidics and lab-on-a-chip devices, (2) improve the fundamental understanding of microfluidic and nanofluidic phenomena, and (3) discuss applications of microfluidics, nanofluidics and lab-on-a-chip devices. Topics covered in this journal include:
1.000 Fundamental principles of micro- and nanoscale phenomena like,
flow, mass transport and reactions
3.000 Theoretical models and numerical simulation with experimental and/or analytical proof
4.000 Novel measurement & characterization technologies
5.000 Devices (actuators and sensors)
6.000 New unit-operations for dedicated microfluidic platforms
7.000 Lab-on-a-Chip applications
8.000 Microfabrication technologies and materials
Please note, Microfluidics and Nanofluidics does not publish manuscripts studying pure microscale heat transfer since there are many journals that cover this field of research (Journal of Heat Transfer, Journal of Heat and Mass Transfer, Journal of Heat and Fluid Flow, etc.).
