Coherent Structure Transport in Turbulent Axisymmetric Pipe Expansions
Jibu Tom Jose, Gal Friedmann, Omri Ram
Turbulent separated flows in axisymmetric expansions can sustain fundamentally different transport organization despite nearly identical mean topology. Using stereo-PIV and time-re…

Effect of Expansion Geometry on Turbulence in Axisymmetric Pipe Flows
Jibu Tom Jose, Gal Friedmann, Dvir Feld +1
We investigate the influence of expansion geometry on the flow field and turbulence structure in axisymmetric pipe flows through comparative analysis of abrupt () and gra…

On the application of refractive index matching to study the buoyancy-driven motion of spheres
Jibu Tom Jose, Aviel Ben-Harosh, Omri Ram
Refractive index matching (RIM) is a powerful tool for multiphase flow studies as it eliminates optical distortions and enables high-fidelity tomographic measurements near solid-fl…
