Through the application of tomographic time-resolved imaging and the utilization of index-matching techniques, our research can overcome previous limitations, enabling high-quality measurements of high-speed flow in circular pipes. The knowledge gained from our work has wide-ranging applications, from engineering and manufacturing to oil and gas and environmental sustainability, fostering advancements and improvements across various industries.

It was found that the inception of attached cavitation on curved surfaces or hydrofoils at incidence is relatively insensitive to the concentration of free stream nuclei due to the local formation microbubbles that act as local nucleation sites. 

We showed that stiff porous media can be modeled as a first-order low pass filter acting on the pressure pulse that propagates through the porous medium following the impingement of normal shock waves. 

Our study delves into the evolution of shockwaves downstream of area expansions, unveiling a complex flow field with multiple shock reflections, vortex formations, and interactions. By dissecting these phenomena, we gain profound insights into the mechanisms governing transient feature decay during shock propagation

Fine water films form during gravity-induced oil-water separation. the films persist in the oil for a long time until they break up leading to the formation of fine water droplets that remain suspended in the oil.
