Abstract

We consider a coupled Patlak-Keller-Segel-Navier-Stokes system in $\mathbb{R}^2$ that describes the collective motion of cells and fluid flow, where the cells are attracted by a chemical substance and transported by ambient fluid velocity, and the fluid flow is forced by the friction induced by the cells. The main result of the paper is to show the global existence of free-energy solutions to the 2D Patlak-Keller-Segel-Navier-Stokes system with critical and subcritical mass.

具有临界和亚临界质量的二维patak - keller - segel - navier - stokes系统自由能解的整体存在性

我们考虑$\mathbb{R}^2$中的耦合patak - keller - segel - navier - stokes系统，该系统描述细胞和流体流动的集体运动，其中细胞被化学物质吸引并通过环境流体速度运输，流体流动由细胞引起的摩擦强迫。本文的主要结果是证明了具有临界和亚临界质量的二维patak - keller - segel - navier - stokes系统的自由能解的全局存在性。

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.
