In physics, fluid dynamics is a subdiscipline 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 (the study of 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. Some of its principles are even used in traffic engineering, where traffic is treated as a continuous fluid, and crowd dynamics.
Fluid dynamics offers a systematic structure—which underlies these practical disciplines—that embraces empirical and semi-empirical laws derived from flow measurement and used to solve practical problems. The solution to a fluid dynamics problem typically involves calculating various properties of the fluid, such as flow velocity, pressure, density, and temperature, as functions of space and time.
On a stream of water you can levitate light balls of all sizes and even disks and cylinders. The mechanism is not the Bernoulli effect... Want to make this at home: My friend Blake from InnoVinci emailed me with a cool idea for a video and footage of levitating balls in water streams. Initially it was tough to explain the physics of what was going on. The standard Bernoulli effect relies on the object being completely immersed in the upward-flowing fluid. But in this case the water seems to form a single stream around the object and it's deflected away and down from the stream. By Newton's third law, the force on the water by the ball is equal and opposite to the force of the water back on the ball, pushing it up into the stream. There is a stable equilibrium position because if the ball...

Hydrodynamic Modelling of current and water level analysis to be used in a design basis is in this example carried out using MIKE 21 HD/FM. The hydraulic conditions determined from this model throughout the fjord are illustrated with MIKE Animator.

Here is a little water star I made for you. It has NiTi wire, KOh and a vinyl coated water resistant "graphene" hood on top. The idea was experimenting with a catalytic condom. ;) Initially there seems to be an exothermic reaction with the NiTi that creates an UN-confirmed transmutation in the metal. This process initiated the bright sun like object you see. There is still so much to do and this was just part of generating hydrodynamic plasma reactions 101 for me. I have some observational discoveries that would not be possible if not for the many teachers this world has to offer. This entire process took about an hour and eighteen minutes and the EMF never rose above ~250 Watts. Thanks as always for watching. I accidentally made this a Standard YouTube License... There is far more t...
The Delft Systematic Yacht Hull Series (DSYHS) has been started in 1973 by professor J. Gerritsma, in cooperation with N. Newman and J. Kerwin of the Massachusetts Institute of Technology (MIT). The aim was to perform measurements on a series of systematically varied yacht hulls, in order to assess the influence of the varied parameter on the hydrodynamic performance (resistance, seakeeping etc.) of a sailing yacht hull. Model SYSSER 50 is part of this series and its Experimental Data is available on DSYHS Database website (Granted by DSYHS.tudelft.nl). Comparison between XFlow CFD Analysis and Experimental Data demonstrates XFlow's exceptional levels of reliability.
