Fluid Particles: A Review

摘要

The concept of fluid particle is fundamental to study the Physics of fluid flow. Three types of fluid particles are currently used: the finite, the infinitesimal and the point particle. The finite particle renders the atomic-molecular structure of matter and is particularly relevant in flow measurements. The infinitesimal and the point concepts are mathematical abstractions used in modeling fluid flow. The subject is reviewed on the basis of well-known fluid flow related textbooks (all in English), comprising authors of different backgrounds and spanning over fifty years of editions
