Fluid dynamics print that page

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 | 2011/10/1 3:59:26

Computational fluid dynamics print that page


The fundamental basis of almost all CFD problems are the Navier–Stokes equations , which define any single-phase fluid flow. These equations can be simplified by removing terms describing viscosity to yield the Euler equations . Further simplification, by removing terms describing vorticity

Circulation (fluid dynamics) print that page

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 | 2011/4/26 14:01:41

Geophysical fluid dynamics print that page


former leads to the Navier-Stokes equations . Further approximations are generally made. First, the fluid is assumed to be incompressible . Remarkably, this works well even for a highly compressible fluid like air as long as sound and shock waves can be ignored. Second, the fluid is assumed

Euler equations (fluid dynamics) print that page

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 | 2011/5/24 10:49:45

Von Karman Institute for Fluid Dynamics (VKI) print that page


The von Karman Institute for Fluid Dynamics is a non-profit educational and scientific organization which specializes in three specific fields: aeronautics and aerospace, environment and applied fluid dynamics, turbomachinery and propulsion. Founded in 1956 , it is located in Sint-Genesius

Fluid mechanics print that page


The study of fluid mechanics goes back at least to the days of ancient Greece , when Archimedes investigated fluid statics and buoyancy and formulated his famous law known now as the Archimedes' Principle . Rapid advancement in fluid mechanics began with Leonardo da Vinci (observation

Slosh dynamics print that page

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 | 2011/8/21 16:07:33

Magnetorheological fluid print that page


A magnetorheological fluid (MR fluid ) is a type of smart fluid in a carrier fluid , usually a type of oil. When subjected to a magnetic field , the fluid greatly increases its apparent viscosity , to the point of becoming a viscoelastic solid. Importantly, the yield stress of the fluid

Volumetric flow rate print that page

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 | 2011/5/4 15:03:19
