摘要

研究了重叠狭窄对动脉血流特性的影响。血液已经被一些应激液代替了。对流动方程进行了线性化处理,导出了压降、流动阻力和壁面剪应力的表达式。结果用图形表示。观察到,随着狭窄的高度和长度的增加,流动阻力、压降和壁面剪应力均增大。注意到随着应力流体参数的耦合,流动阻力和压降减小。壁面剪应力随应力流体参数的变化而增大。

Investigation of blood flow through an artery in the presence of overlapping stenosis
The effects of an overlapping stenosis on blood flow characteristics in an artery have been studied. Blood has been represented by a couple stress fluid. The flow equations have been linearised and the expressions for pressure drop, resistance to the flow and wall shear stress have been derived. The results are shown graphically. It is observed that the resistance to the flow, pressure drop and wall shear stress increases with height and length of the stenosis. And it is noticed that the resistance to the flow and pressure drop decreases with couple stress fluid parameters. But wall shear stress increases with couple stress fluid parameters.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
