A crucial step in wine tasting is the so called swirling, necessary to release the bouquet of the wine: a gentle circular movement of the glass generates a wave propagating along the glass walls, enhancing oxygenation and mixing. Although being used in a large variety of other applications (eg cells cultures in orbital shaken bioreactors) this motion is not yet well understood. In this fluid dynamics video we show the large variety of waves shapes generated by this simple movement, and we identify a group of dimensionless parameters governing the flow.

Almost everything out there is spinning around: stars, galaxies, planets, moons - they are all rotating. Yet physicists believe that the universe itself is not revolving. Why? Mazur, a physicist at the University of South Carolina in Columbia, is one of a number who think it is entirely possible that our universe is spinning on an axis. You could stop worrying about the big problems in cosmology: the origin of the big bang, the nature of dark energy and maybe dark matter too, also superfast period of expansion known as inflation. Is it so hard to let the cosmos spin? This Paradigm is in line with James Clerk Maxwell's concept that the universe is existing in a dynamic medium that has many properties very much like those found in fluids such as water or the Earth's atmosphere, with respect to the energy movements found there. "Implosion is no invention in the conventional sense, but rather the renaissance of ancient knowledge, lost over the course of time." * Implosion Magazine, No. 83, p.16 "You must learn to think one octave higher.

My endeavor to catalog and video typical hydrodynamics seen in Pontoon Operation. Benefits: 1. Why BIG FOOT gearcases exist 2. Why Ventilation in turns occurs 3. Why Performance Strakes, Specialized Nose Cones and Spray shields vary, along with Underdeck Skins. It will also illustrate that a mere 5 mph difference is quite a difference! This first video installment is: (2) two-log Pontoon Boat operation. Video endeavors to show 0 mph, 5 mph, 10 mph, 15 mph & 20 mph shots, with detailed speed variations that focus on cone design, cone spray shield, and motor pod design. (Test vehicle was a 20ft pontoon boat with 25inch logs, no Performance Strakes, No Underbelly "WaveTamer" skin, a pretty common pontoon design in 2011) Our next video installments will show two-log pontoons with WaveTamer and Performance Strakes, and even later a triple-log tri-toon operation, and how they vary in spray and turbulence. We hope that the audience will observe and recognize that pontoons, unlike V-Hull boats, squeeze the water and spray inward. This causes a great deal of turbulence. So a motor must reach down deeper into the water to escape the aerated water, or it is forced to ventilate in the aeration. Moreover, higher speeds above 15mph begin to benefit from lifting strakes and underbelly skin. Even there, we'll endeavor to show the differences in design, cause & effect between strakes and WaveTamer underbelly skin.

The third and final hydrodynamics test at Newcastle University's MAST towing tank. The aims of the test were to evaluate the drag curve of the now finished hull shape, determine the drag induced by the drivetrain(s) and collect some data to help decide on rudder size. It was also a good chance to test our waterproof video camera! This work wouldn't have been possible without the unwavering support of John Burn Ltd, CGI, Bentley Motors and Newcastle University. Thanks to all those who have made this testing a success. We're still crunching through the data, but the numbers are looking very, very good!

Shark skin produces propulsion: hydrodynamic function and biomimetic applications Video: Researchers crafted a flapping foil made with shark skin and wiggled it through the water as if a shark were swimming, shown in video as well. [Video of shark experiment - www.livescience.com - Shark skin produces propulsion jeb.biologists.org - Sharks' Scales Create Tiny Whirlpools for Speedy Swimming www.livescience.com Reference The hydrodynamic function of shark skin and two biomimetic applications J Exp Biol March 1, 2012 215, 785-795. doi: 10.1242/?jeb.063040 jeb.biologists.org SUMMARY It has long been suspected that the denticles on shark skin reduce hydrodynamic drag during locomotion, and a number of man-made materials have been produced that purport to use shark-skin-like surface roughness to reduce drag during swimming. But no studies to date have tested these claims of drag reduction under dynamic and controlled conditions in which the swimming speed and hydrodynamics of shark skin and skin-like materials can be quantitatively compared with those of controls lacking surface ornamentation or with surfaces in different orientations. We use a flapping foil robotic device that allows accurate determination of the self-propelled swimming (SPS) speed of both rigid and flexible membrane-like foils made of shark skin and two biomimetic models of shark skin to measure locomotor performance. We studied the SPS speed of real shark skin, a silicone riblet material with evenly spaced <b>...</b>

This series helps teachers demystify physics by showing students what it looks like. Field trips to hot-air balloon events, symphony concerts, bicycle shops, and other locales make complex concepts more accessible. Inventive computer graphics illustrate abstract concepts such as time, force, and capacitance, while historical reenactments of the studies of Newton, Leibniz, Maxwell, and others trace the evolution of theories. The Mechanical Universe helps meet different students' needs, from the basic requirements of liberal arts students to the rigorous demands of science and engineering majors. video.google.com This series is also valuable for teacher professional development.

Not being aware of scientists "proving" it cannot fly, the bumblebee succeeds under "the power of its own ignorance". The origin of this myth has been difficult to pin down with any certainty.

This simulation uses a flux-limited diffusion solver to explore the radiation hydrodynamics of early galaxies, in particular, the ionizing radiation created by Population III stars. At the time of this rendering, the simulation has evolved to a redshift of 3.5. The simulation volume is 11.2 comoving megaparsecs, and has a uniform grid of 10243 cells, with over 1 billion dark matter and star particles. This animation shows a combined view of the baryon density, dark matter density, radiation energy and emissivity from this simulation. The multi-variate rendering is particularly useful because is shows both the baryonic matter ("normal") and dark matter, and the pressure and temperature variables are properties of only the baryonic matter. Visible in the gas density are "bubbles", or shells, created by the radiation feedback from young stars. Seeing the bubbles from feedback provides confirmation of the physics model implemented. Features such as these are difficult to identify algorithmically, but easily found when viewing the visualization. Simulation was performed on Kraken at the National Institute for Computational Sciences. Visualization was produced using resources of the Argonne Leadership Computing Facility at Argonne National Laboratory.

Kristof, P., Benes, B., Krivanek, J., & Stava, O. This paper presents a new technique for modification of 3D terrains by hydraulic erosion. It efficiently couples fluid simulation using a Lagrangian approach, namely the Smoothed Particle Hydrodynamics (SPH) method, and a physically-based erosion model adopted from an Eulerian approach. The eroded sediment is associated with the SPH particles and is advected both implicitly, due to the particle motion, and explicitly, through an additional velocity field, which accounts for the sediment transfer between the particles. We propose a new donor-acceptor scheme for the explicit advection in SPH. Boundary particles associated to the terrain are used to mediate sediment exchange between the SPH particles and the terrain itself. Our results show that this particle-based method is efficient for the erosion of dense, large, and sparse fluid. Our implementation provides interactive results for scenes with up to 25000 particles.

This experiment gives you an idea about packed columns , effects of gas and liquid flow rates on the pressure drop developed. You can plot pressure drop vs gas flow rate keeping liquid flow rate as parameter and obtain loading and flooding points. Also, this experiment tells that how packing properties can be critical in the design of a packed column. You can find out void fraction, types of the packing and packing surface by doing separate measurements for them.

From the paper "Bulgeless dwarf galaxies and dark matter cores from supernova-driven outflows," by F. Governato, C. Brook, L. Mayer, A. Brooks, G. Rhee, J. Wadsley, P. Jonsson, B. Willman, G. Stinson, T. Quinn & P. Madau. Nature 13 january 2010. dx.doi.org The properties of 'dwarf' galaxies have long challenged the cold dark matter (CDM) model of galaxy formation, as the properties of most observed dwarf galaxies contrast with models based on the dominance of CDM. Here, hydrodynamical simulations (assuming the presence of CDM) are reported in which the analogues of dwarf galaxies — bulgeless and with shallow central dark-matter profiles — arise naturally. The movie is from computer simulations using SPH Treecode Gasoline. A fully parallel, N-body+smoothed particle hydrodynamics (SPH) code GASOLINE is used to compute the evolution of both the collisionless and dissipative component in the simulations. A detailed description of the code is available in the literature. Here we recall its essential features. GASOLINE computes gravitational forces using a treecode that employs multipole expansions to approximate the gravitational acceleration on each particle. A tree is built with each node storing its multipole moments. Time integration is carried out using the leapfrog method, which is a second-order symplectic integrator requiring only one costly force evaluation per timestep and only one copy of the physical state of the system.

This is the first scene from a simple CUDA implementation of SPH using simple "bucket" grid to speed up queries. The wall provides a tangential force in order to keep motion going. Adjusting viscosity too high will produce instability as shown. Since this makes only a single density estimation, a high rest density setting will tend to coalesce into local globules. (Actually these grouping tend to occur at the grid sites. To do.) Based on the paper by Takahiro Harada of Tokyo University.

Eonfusion's multi dimensional data structure model and customised flood module have been tailored to modelling the hydrodynamics of flood waters and the process of inundation. The flood module leverages GPU technology to model and capture the trajectories of millions of smoothed-particles added by the user in the interactive real-time model environment. Model results can be visualised as the particle trajectories or summarised in time varying (3D) rasters containing water depth, velocity and heading. The use of GPU technology and the ability to handle several hundred million data records at one time allows Eonfusion to effectively model flood water dynamics and integrate important contextual data for a holistic view.

These videos are captured in realtime, and this program can get 58-60 FPS running 4000 particles because it processes in parallel. I wrote this program in .net. The engine is a dll that processes data in parallel on any CUDA compatible NVIDIA graphics card (8800 GT, Tesla etc). Each video features thousands of particles ~5000 - 8000. These would be painfully slow running in series. The program is still being developed--more or less as a hobby. kbingham.net
