WebIn this contribution, different 3D numerical approaches are applied in order to simulate the behaviour of turbulent flow through a rectangular channel with broad-crested weirs. In addition, water flow velocities, using Acoustic Doppler Velocimetry (ADV) instrumentation, were recorded. Two turbulence quantities are estimated using the laboratory records … WebExtreme events in computational turbulence. Yeung, P. K. ; Zhai, X. M. ; Sreenivasan, Katepalli R. In the last decade or so, massive computations of turbulence performed by …
