Slow 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...

متن کاملCFD ANANLYSIS OF THE MATIS-H EXPERIMENTS ON THE TURBULENT FLOW STRUCTURES IN A 5x5 ROD BUNDLE WITH MIXING DEVICES
The measurements of a turbulent swirl flow in the subchannels of a 5 x 5 rod array having typical mixing devices at the MATIS-H (Measurements and Analysis of Turbulence In SubchannelsHorizontal) facility have been analysed using a commercial CFD code of STAR-CCM+ 4.02 with a unit grid model having no unmatched grid interface. The main objectives of this analysis is to establish a proper CFD ana...
متن کاملExperimental characterization of extreme events of inertial dissipation in a turbulent swirling flow
The three-dimensional incompressible Navier-Stokes equations, which describe the motion of many fluids, are the cornerstones of many physical and engineering sciences. However, it is still unclear whether they are mathematically well posed, that is, whether their solutions remain regular over time or develop singularities. Even though it was shown that singularities, if exist, could only be rar...
