Silvia Matt rated it it was amazing Aug 13, Jim Uschock rated it it was amazing Jun 02, To describe this complex type of behaviour, it is common to consider the statistics of the flow quantities: Published May 1st by Parabolic Press, Incorporated.

The controller is then turned off, and one can follow the system’s state and energy returning to the uncontrolled dynamics.

For more details, have a look at the paper, which we dyks with the aim to have it readable by non-specialists as well An album of fluid motion Flapping flag Self ah wave Optimization for sensitivity analysis Atomization: Zahra Khan rated it really liked it Jul 07, This is what happens when driving a bicycle.

We are here insterested in the sensitivity of a pipe filled with a fluid, that has a localized diameter constriction. Thanks to a recursive solution technique, this equation can be solved very efficiently. 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 ydke back the excitement of chaos to boring blandness.


Let us consider a three dimensionnal array of random numbers.

Want to Read saving…. To test this method, we look at a free shear layer. Mechanics of Active Miltno Edin Skaljic rated it it was amazing Sep 05, Here showing the channel dynamics for several random initial conditions: Jeff Wilsbacher rated it really liked it Jun 01, A biphasic computational model for simulations of blood-perfused tissue. The Consequences of Explosive Vaporization.

Dynamics of single bubble under sub-cooled flow boiling. Indeed, the system is unstable: Flows ranging from creeping to hypersonic speeds, in both the laboratory and Nature, are observed directly, or made visible using smoke, ink, bubbles, particles, shadographs, schlieren, interferometry, and other techniques.

Debunking the two-dimensional assumption on infinitely long wings. The system dynamics is then composed of: We can compute the initial perturbation of a time evolution, that lead at a given time T to the maximum possible growth.

After that, we visualize the computationnal grid cells, adapting to the interface displacement. An other approach is to solve the equations that governs the statistics itself.

Falling jet of dry granular material in water. To build this filter, we solve numerically a linear system of equations known as the Yule-Walker equation. The structure and origin of confined Holmboe waves. The flag in the wind flaps, and this is an active topic of research to understand how a flow and an elastic body interact and promote instability.

A typical application is in combustion: A compliant surface move in reaction to the flow pressure, like for instance the skin of cluid dolphin when he swims. From streams to plumes. The energy of the estimation error, which is a measure of the estimation quality is shown.


Once this region traversed, the system is locally stable again and the amplitude of the flow starts decaying.

Est-ce que c’est convainquant? Laura Watkins rated it liked it Mar 31, The perturbations come from road irregularities, wind and so on. Momentum and strain energy transfer in structurally flexible pitching hydrofoil. Flow patterns in urban neighborhoods under hurricane force winds.

Gliding with body undulations: Collective hydrodynamic communication through ultra-fast cellular contractions. Here these iterations converge finally to the initial condition that has the largets energy growth for the target time T. If selected for publication as a Gallery winner, it is expected that normal copyright practices will be followed either APS will be granted copyright of the images that can be reused by the author in other publications with appropriate attribution of original work, or if published in another journal prior to winning Gallery articles, the authors will secure similar authorization prior to being accepted for publication in the Gallery.

Pour faire un article scientifique, il y a tout un tas d’obstacles et besoin d’un grand nombre de savoir-faire. While in Genova, we started a project on this with Alessandro Bottaro and julien Favier, but instead of looking at instabilities like it is usually done, we compute – using optimization methods – the initial conditions that lead to a large energy growth.
