Facilities

Experimental facilities and measurement systems I have designed, built or established. Most of my research depends on infrastructure I helped create.

Transient Fluid Mechanics Laboratory

Technion · co-established with Asst. Prof. Omri Ram

Developed the laboratory from a temporary space into a fully equipped research facility with capabilities for advanced flow measurements, multiphase experiments and shock-driven flows.

Shock tube

Technion · designed, built and automated

A 7 m shock tube, including the electronics, sensor integration, multi-instrument synchronization, motorized traversal and LabVIEW/Arduino control. Its control system remains the core of the facility, which now runs with new test sections.

Used in: shock-driven flows

Rendering of a closed-loop water tunnel with pipework and a test section — Closed-loop water-tunnel facility. From Zuckerman, Jose, Levi & Ram, arXiv (2026).

Recirculating water tunnel

Technion · specified, instrumented and calibrated

Specified the flow quality, instrumented and calibrated the laboratory’s large recirculating water tunnel, establishing its operating envelope.

Used in: flow over protrusions

Four high-speed cameras around a tall transparent tank — Tomographic PTV setup around the octagonal tank. From Jose, Ben-Harosh & Ram, Int. J. Multiphase Flow (2026).

Refractive-index-matched tomographic PTV

Technion · established

Time-resolved, four-camera tomographic particle tracking with refractive-index matching, for freely moving and optically hidden bodies. It is the measurement platform behind LE-DM.

Used in: freely moving bodies, LE-DM

3D surface plot of a scanned liquid surface around a hexagonal particle — Raw scan around a flat hexagonal particle (displacement magnified 10 times). From Einhorn, Jose, Zigelman et al., J. Fluid Mech. (2025).

Liquid–gas interface scanning

Technion · designed and built

A fluorescence-based laser-sheet scanning system with stereo imaging that maps the shape of a liquid–gas interface with 0.1 mm precision.

Used in: liquid–gas interfaces

Tomographic and PSF-engineered imaging

Technion · built

A five-camera system combining tomographic and PSF-engineered imaging, used to validate a single-camera 3D PIV method based on wavefront shaping and deep learning.

Used in: monocular 3D PIV (under review)

Boiling facilities

Technion · contributed

Contributed to the design of single- and multi-bubble boiling facilities. Currently involved in confined-cell experiments on boiling and bubble-driven convection, using digital holography to track bubble growth and evolution.

Diagrams of an airfoil test section with cameras, laser sheet and drive train — Pitching-airfoil test section and stereo PIV arrangement in the tunnel. From Jose, Lu, Agarwal & Katz, AIAA J. (2026).

Refractive-index-matched water tunnel

Johns Hopkins University · designed and built

A large refractive-index-matched recirculating water tunnel using more than 2,000 L of sodium iodide solution, including the mixing plant, storage, pressure and vacuum control, an inline cyclone bubble separator and hydraulic calibration.

Used in: dynamic stall
