Fluid mechanics is a branch of physics related to the mechanics of fluids (liquids, gases and plasmas) and the forces exerted on them. Fluid mechanics has a wide range of applications, including mechanical engineering, civil engineering, chemical engineering, biomedical engineering, geophysics, astrophysics and biology. Fluid mechanics can be divided into fluid static, study of resting fluids; and fluid dynamics, the study of the effect of forces on the movement of the fluid. It is a branch of continuous mechanics, a theme that models matter without using information that it is made of atoms; that is, it models the matter from a macroscopic rather than a microscopic point of view. Fluid mechanics, especially fluid dynamics, is an active research field with many problems that are partially or totally unresolved. Fluid mechanics can be mathematically complex and can be best solved by numerical methods, usually using computers. A modern discipline, called Computational Fluid Dynamics (CFD), is dedicated to this approach to solve problems of fluid mechanics. Particle image velocimetry, an experimental method for visualizing and analyzing fluid flow, also takes advantage of the highly visual nature of fluid flow.
