Abstract

. The behaviour of platelet ﬂows in plasma and the change of the platelet surfaces is studied by numerical simulations. In particular, the inﬂuence of the 2D platelets surface roughness and Reynolds number on the rotation of platelets is con-sidered. Reynolds numbers Re vary from 0.4 to 50 and it is noted that if Re = 50, the 2D platelets stop rotating after 90 ◦ turn. If 0.4 ≤ Re ≤ 20, the rotation period increases along with the increase of Reynolds number. The maximum angular velocity, the mini-mum angular velocity and the rotation period of platelets depends on their roughness. However, these characteristics are little affected by the roughness if the Reynolds number is close to 1. It is also worth noting that the torque of 3D platelets is greater than the torque of 2D platelets.

不同雷诺数剪切流中悬浮粗糙血小板的动力学

．通过数值模拟研究了血小板在血浆中的流动行为和血小板表面的变化。特别考虑了二维血小板表面粗糙度和雷诺数对血小板旋转的影响。雷诺数Re从0.4到50不等，值得注意的是，如果Re = 50, 2D血小板在90◦转角后停止旋转。当0.4≤Re≤20时，旋转周期随着雷诺数的增加而增大。血小板的最大角速度、最小角速度和旋转周期取决于其粗糙度。然而，当雷诺数接近1时，粗糙度对这些特性的影响很小。同样值得注意的是，3D血小板的扭矩大于2D血小板的扭矩。

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.
