A remark on constrained von Kármán theories.
We derive the Euler-Lagrange equation corresponding to 'non-Euclidean' convex constrained von Kármán theories.
متن کاملSuperfluid high REynolds von Kármán experiment.
The Superfluid High REynolds von Kármán experiment facility exploits the capacities of a high cooling power refrigerator (400 W at 1.8 K) for a large dimension von Kármán flow (inner diameter 0.78 m), which can work with gaseous or subcooled liquid (He-I or He-II) from room temperature down to 1.6 K. The flow is produced between two counter-rotating or co-rotating disks. The large size of the e...
متن کاملSpatio-Temporal Chaos and solitons Exhibited by von kÁrmÁn Model
Forced oscillations of flexible plates with a longitudinal, time dependent load acting on one plate side are investigated. Regular (harmonic, subharmonic and quasi-periodic) and irregular (chaotic) oscillations appear depending on the system parameters as well as initial and boundary conditions. In order to achieve highly reliable results, an effective algorithm has been applied to convert a pr...
متن کاملSolvability of Dynamic Contact Problems for Elastic von Kármán Plates
The existence of solutions is proved for unilateral dynamic contact problems of elastic von Kármán plates. Boundary conditions for a free and clamped plate are considered.
متن کاملSlow dynamics in a turbulent von Kármán swirling flow.
An experimental study of a turbulent von Kármán flow in a cylinder is presented. The mean flow is stationary up to a Reynolds number Re=10(4) where a bifurcation takes place. The new regime breaks some symmetries of the problem and becomes time dependent because of equatorial vortices moving with a precession movement. In the exact counterrotating case, a bistable regime appears and spontaneous...
