TL;DR: In this paper, an experimental study about the velocity, size and concentration of ultrasonic cavitation bubbles is presented, where a 20 kHz horn dipping vertically into a liquid container is used to provide an experimental analysis of the system.

TL;DR: An experimental investigation of the size and volumetric concentration of acoustic cavitation bubbles is presented and difficulties arising in the application of the laser diffraction technique are discussed: in particular, the fact that the acoustic wave disturbs the light scattering patterns even when there are no cavitationbubbles along the measurement volume is investigated.

TL;DR: In this article, a brief summary of techniques for nanoparticle removal in waters and wastewaters is presented, but it seems that no treatment can absolutely protect the public from exposure to a large-scale dissemination of nanomaterials.

TL;DR: In this paper, a simulation based on the URANS equations and a Large Eddy Simulation with the Smagorinski subgrid scale model are compared to PIV data in terms of velocity, kinetic energy and turbulence dissipation rate.

TL;DR: In this paper, an experimental device of an upward co-current oil-in-water dispersed flow (viscosity ratio λ ≈ 0.5 ) in a vertical column equipped with a concentric orifice has been designed.
