Turbulence models | Computational fluid dynamics
Detached eddy simulation (DES) is a modification of a Reynolds-averaged Navier–Stokes equations (RANS) model in which the model switches to a subgrid scale formulation in regions fine enough for large eddy simulation (LES) calculations. (Wikipedia).
AWESOME Eddy currents (explained)!!!
In this video i show and i explain some examples of eddy currents! Enjoy!
From playlist ELECTROMAGNETISM
Eddy currents are currents which circulate in conductors like swirling eddies in a stream. They are induced by changing magnetic fields and flow in closed loops, perpendicular to the plane of the magnetic field. They can be created when a conductor is moving through a magnetic field, or wh

AWESOME Physics demonstrations. Interference of water waves experiment.
A ripple tank is placed above a mirror and a projection screen. Two synchronous point sources, whose frequency can be varied, tap the surface of the water and produce circular waves. The interference pattern of the waves including the lines of nodes can be observed on the screen.

Turbulence Closure Models: Reynolds Averaged Navier Stokes (RANS) & Large Eddy Simulations (LES)
Turbulent fluid dynamics are often too complex to model every detail. Instead, we tend to model bulk quantities and low-resolution approximations. To remain physical, these reduced approximations of the Navier-Stokes equations must be "closed", and turbulence closure modeling is one of t

Show Me Some Science! Constructive and Destructive Interference
Waves are one way in which energy can be send down a string. When two waves meet, they interact. This interaction is called interference. If two waves add up this is known as "constructive interference" and if they cancel out it's "destructive interference". After the waves interact, they
