Abstract

The collision between solids in fluid is common in engineering, but the numerical simulation method is less studied. A direct numerical simulation method combining the sharp interface immersed boundary method and the finite element method based on penalty function was established for solid-solid collision and coupling with fluid. The lubrication model for cylinder structures with and without fluid flow was developed using the data regression method. The partitioned coupling algorithm was used to realize the coupling solution between the fluid and solid domains. Four numerical examples were presented to demonstrate the validity of the established method. The numerical simulation of the vortex-induced collisions between two side-by-side cylinders showed the capabilities of the proposed method.

固体-固体碰撞与流体耦合的直接数值模拟方法

流体中固体之间的碰撞在工程中很常见，但数值模拟方法研究较少。将锐界面浸入边界法和基于罚函数的有限元法相结合，建立了固-固碰撞与流体耦合的直接数值模拟方法。采用数据回归方法建立了有液流和无液流圆柱结构的润滑模型。采用分区耦合算法实现了流体与固体区域的耦合求解。通过四个算例验证了该方法的有效性。对两个并排圆柱体之间涡流诱导碰撞的数值模拟表明了该方法的能力。

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.
