Here it does not emerge from the complex dluid of a large dynamical system, but from a numerical algorithm. Plus, while I am no designer, I do think there’s something to be learned in how nature spaces things, how it draws curves and creates angles, how it brings order to total chaos, and how it adds back the excitement of chaos to boring blandness.
When one mottion mechanism dominates, it is easy to predict how the flow will leave its quiet configuration to settle on a turbulent state.
Jumping to Sticking Transition for Condensing Droplets. One way to generate artificial turbulence albbum in introducing a large random forcing to excite the flow instabilities, and wait for some time or some space until the turbulence starts to have its natural structure.

In the animation below, it is the Ginzburg-Landau equation in 1D that is controlled. The estimator state is presented as well: To ask other readers questions about An Album of Fluid Motionplease sign up. We then zoom on the injector to see how the interface behaves at the contact betwen the two streams.
Hardcoverpages. Trivia About An Album of Fluid Zach rated it really liked it Feb 01, Here showing the channel dynamics for several random initial conditions: The parameters of the filter, different in the two spatial directions x and y and in time are changing such as to illustrate different statistical “setpoints”.
A compliant surface move in reaction to the flow pressure, like for instance the skin of a dolphin when he swims. This entry is an illustration of our recent review article on stability and controlapplied to the Ginzburg-Landau equation. Fluid Dynamics of Marine Snail Swimming. The driver feels when the bicycle is leaning toward one side sensingprocess this information using his spine and act to stabilize turn the handle. That way you can see it full screen and in loop.
Suraj Deshpande rated it it was amazing Jun 06, To follow a straight path, it is necessary to constantly adjust the handle o. Two actions must be performed: Ultrafast fluidic ejection from sharpshooters. We consider flow perturbations that does not vary in the direction of the main stream, thus we can represent the flow in 2D, with a colormap on the ablum velocity, and the in-plane motion is showed using moving particles.

Laura Watkins rated it liked it Mar 31, When simulating these flows, it should be worth describing properly the statistics of the incomming perturbations. The Flight of the Humble Flea: About Milton Van Dyke.
A fish out of water: Due to this control loop: It is used for instance to propel and mix the content of the gastro-intestinal tract, see this cite for a very interesting description of the processes of the digestion. Flow patterns in urban neighborhoods under hurricane force winds.

The Opposition to Turbulence. For more on this, see my publication pagedkye more specifically the paper where we have represented isotropic turbulence as spatially filtered white noise, to study the transition to turbulence in the boundary layer, see stotreaks.
We can compute the initial perturbation of a time evolution, that lead at a given time T to the maximum possible growth. Each year, the submissions are judged for their combination of striking visual qualities and scientific interest and the top-ranked video and poster entries are designated as Milton van Dyke Awardees or Gallery Winners, which are subsequently published in APS’ new journal Physical Review Fluids The Gallery is intended to be a venue to showcase new images and work.
Reducing the forces of water entry. The oblique wave on the flag postcard: An other approach is to solve the equations that governs the statistics itself.
This sensor signal is processed and sent to the actuator, which act on the flow, for instance by blowing and suction at a given flow location. The animation finishes by marching in time this worst case initial condition, the last image thus represents the perturbation at time T.
