Outline of fluid dynamics

The following outline is provided as an overview of and topical guide to fluid dynamics:

In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids – liquids and gases. It has several subdisciplines, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of water and other liquids in motion). Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, determining the mass flow rate of petroleum through pipelines, predicting weather patterns, understanding nebulae in interstellar space and modelling fission weapon detonation.

Below is a structured list of topics in fluid dynamics.

What type of thing is fluid dynamics?

Fluid dynamics can be described as all of the following:

• An academic discipline – one with academic departments, curricula and degrees; national and international societies; and specialized journals.
• A scientific field (a branch of science) – widely recognized category of specialized expertise within science, and typically embodies its own terminology and nomenclature. Such a field will usually be represented by one or more scientific journals, where peer-reviewed research is published.
  • A natural science – one that seeks to elucidate the rules that govern the natural world using empirical and scientific methods.
    • A physical science – one that studies non-living systems.
      • A branch of physics – study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force.
        • A branch of mechanics – area of mathematics and physics concerned with the relationships between force, matter, and motion among physical objects.
          • A branch of continuum mechanics – subject that models matter without using the information that it is made out of atoms; that is, it models matter from a macroscopic viewpoint rather than from microscopic.
            • A subdiscipline of fluid mechanics – branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas) and the forces on them.
    • A biological science – field that studies the role of physical processes in living organisms. For an example of a biological area involving fluid dynamics, see hemodynamics.
