## Fluid dynamics

In physics , **fluid** dynamics is a sub-discipline of **fluid** mechanics that deals with **fluid** flow —the natural science of fluids ( liquids and gases ) in motion. It has several subdisciplines itself, including aerodynamics (the study of air and other gases in motion) and hydrodynamics

## Circulation (fluid dynamics)

In **fluid** dynamics , circulation is the line integral around a closed curve of the **fluid** velocity . Circulation is normally denoted . If is the **fluid** velocity on a small element of a defined curve, and is a vector representing the differential length of that small element, the contribution

## Euler equations (fluid dynamics)

In **fluid** dynamics , the Euler equations are a set of equations governing inviscid flow . They are named after Leonhard Euler . The equations represent conservation of mass (continuity), momentum and energy, corresponding to the Navier–Stokes equations with zero viscosity and heat conduction

## Slosh dynamics

In **fluid** dynamics , slosh refers to the movement of liquid inside another object (which is, typically, also undergoing motion). Strictly speaking, the liquid must have a free surface to constitute a slosh dynamics problem, where the dynamics of the liquid can interact with the container

## Volumetric flow rate

The volumetric flow rate in **fluid** dynamics and hydrometry , (also known as volume flow rate or rate of **fluid** flow ) is the volume of **fluid** which passes through a given surface per unit time (for example cubic meters per second [m 3 s -1 ] in SI units, or cubic feet per second [cu
