Schlieren and BOS velocimetry of a round turbulent helium jet in air
Gary S. Settles, Alex Liberzon
Seedless velocimetry is gaining interest in many industrial and research applications. We report on a comparative study of time-resolved optical velocimetry using traditional, mirr…
OpenPIV-Matlab -- An open-source software for particle image velocimetry; test case: birds' aerodynamics
Hadar Ben Gida, Roi Gurka, Alex Liberzon
We present an open-source MATLAB package, entitled OpenPIV-Matlab, for analyzing particle image velocimetry (PIV) data. We extend the PIV analysis with additional tools for post-pr…
Turbulence -- Obstacle Interactions in the Lagrangian Framework: Applications for Stochastic Modeling in Canopy Flows
Ron Shnapp, Yardena Bohbot-Raviv, Alex Liberzon +1
Lagrangian stochastic models are widely used to predict and analyze turbulent dispersion in complex environments, such as in various terrestrial and marine canopy flows. However, d…
Transient stratification force on particles crossing a density interface
Lilly Verso, Maarten van Reeuwijk, Alexander Liberzon
We perform a series of experiments to measure Lagrangian trajectories of settling and rising particles as they traverse a density interface of thickness using an index-matched…
Extended 3D-PTV for direct measurements of Lagrangian statistics of canopy turbulence in a wind tunnel
Ron Shnapp, Erez Shapira, David Peri +3
Direct estimation of Lagrangian turbulence statistics is essential for the proper modeling of dispersion and transport in highly obstructed canopy flows. However, Lagrangian flow m…
Small scale aspects of flows in proximity of the turbulent/non-turbulent interface
M. Holzner, A. Liberzon, N. Nikitin +2
The work reported below is a first of its kind study of the properties of turbulent flow without strong mean shear in a Newtonian fluid in proximity of the turbulent/non-turbulent…
