Omer Hadar Presents Left-Ventricular Flow Work at ISBME
Omer Hadar presented the lab's left-ventricular flow work at the Israel Society for Biomedical Engineering's annual conference. Omer Hadar, M.Sc. student in the Turbulence Structure Laboratory, presented a poster at the Israel Society for Biomedical Engineering annual conference: “Experimental Quantification of Three-Dimensional, Time-Resolved Fluid–Structure Interaction in a Left-Ventricular Phantom,” co-authored with Noaz Meivar, Shai Avidan, and Alex Liberzon. The work reconstructs 3D...

Eytan Stibbe, the Rakia Mission, and a liquid lens
At a Rakia Mission meeting on space industry-academia collaboration, a conversation with Eytan Stibbe turned to a well-known photograph from the International Space Station. Alex Liberzon took part in a meeting on a roadmap for collaboration between the space industry and academia, organized by the Israel Space Forum together with the Rakia Mission and the Israel Space Agency. There he met Eytan Stibbe. The conversation turned to the well-known photograph of Eytan looking into the camera...

OpenPIV Makes the Slide at a Phantom High-Speed Camera Webinar
A post-processing slide from a Phantom high-speed camera webinar lists OpenPIV right next to LaVision and Dantec — a small, useful data point on who actually uses it. Phantom, the Vision Research high-speed camera line used across many PIV and 3D-PTV labs (including ours), ran a webinar on flow-field post-processing. One slide splits the field into two columns: an open-source column listing OpenPIV, PIVlab, and others, next to a commercial column listing LaVision and Dantec. The open-source...

Omer and Omri Just Returned from the Great Expedition to Tanzania
Lab members Omer Hadar and Omri Kimhi volunteered on a project addressing clean water scarcity in Tanzania, applying their mechanical engineering expertise with Engineers Without Borders (AFRIA) Tel Aviv. The expedition was highlighted in an AFRIA Engineers Without Borders Tel Aviv LinkedIn post — a great example of the lab's engineering skills making a direct impact beyond the research bench.

Omri Kimhi, M.Sc. student in the Turbulence Structure Laboratory, has received a prestigious scholarship from the Smoler-Winikov Fund for Environmental Research. The fund evaluated nearly 50 proposals from across the university, judging them on researcher excellence, proposal strength, and alignment with the fund's priority areas. Omri's research focuses on turbulent scalar and momentum transport in environmental flows, and his proposal was selected as one of the winners. Congratulations,...

Our Lab on the ME Research Day
Omer Hadar presented at the Tel Aviv University School of Mechanical Engineering seminar for prospective master's students, discussing his research on the experimental investigation of three-dimensional flows in the left ventricle, along with an overview of the laboratory's ongoing work.
Read post →We've Been Awarded a New ISF Grant to Build the Most Exciting MEMS Turbulent Flow Sensor Yet
The Israel Science Foundation has funded the development of a new MEMS-based flow sensor designed to investigate the smallest scales of turbulence. This builds on the lab's ongoing collaboration with Prof. Slava Krylov's MEMS laboratory, combining resonant-frequency and snap-through sensing principles into a new generation of flow velocity sensors for turbulence research.

Why Sinking Particles Briefly Rise: A New Equation from the Lab
New research led by Dr. Teddy Lazebnik, Prof. Alex Liberzon, and Ph.D. student Chen Mortenfeld, published in Machine Learning: Science and Technology, shows that particles settling through a fluid can suddenly slow down — and even move upward for a moment — when crossing between layers of different density. Using physics-informed symbolic regression, the team derived a delayed oscillatory closure that captures this transient rise, a phenomenon relevant to sediment transport, marine snow, and...
