Extreme vorticity events in turbulent Rayleigh-Bénard convection from stereoscopic measurements and reservoir computing
High-amplitude events of the out-of-plane vorticity component ω_{z} are analyzed by stereoscopic particle image velocimetry (PIV) in the bulk region of turbulent Rayleigh-Bénard convection in air. The Rayleigh numbers Ra vary from 1.7×10^{4} to 5.1×10^{5}. The experimental investigation is connected...
