Materials Research, 2022 Close-Coupled Gas Atomization (CCGA) is often used to produce spherical metal powders with a wider Particle Size Distribution (PSD) (10 – 500 µm) compared to that required by the main Additive Manufacturing processes (10 – 105 µm).

Atomic hydrogen: the quantum gas [PDF]
Physics World, 1995 It was a complete surprise when Isaac Silvera and his colleagues at the University of Amsterdam observed the existence of a remarkably stable gas of hydrogen atoms in 1979. They found that a gas of the so-called "atom of atoms" could be confined for several minutes in a cryogenic test cell close to absolute zero, provided that the walls were coated ...

Acoustic resonance and atomization for gas-liquid systems in microreactors
Ultrasonics Sonochemistry, 2021 It is shown that a liquid slug in gas–liquid segmented flow in microchannels can act as an acoustic resonator to disperse large amounts of small liquid droplets, commonly referred to as atomization, into the gas phase.

Characterization of Gas Atomized Ni-Mn-Ga Powders
Materials Today: Proceedings, 2015 Gas atomization is a well-known process for obtaining high quality metallic powders. It produces spherical high-density particles with a controllable particle size distribution. We used gas atomization to obtain two different Ni-Mn-Ga powders and investigated their microstructure, transformation temperatures and magnetic properties as well as the ...

Analysis of dynamic acoustic resonance effects in a sonicated gas–liquid flow microreactor
Ultrasonics Sonochemistry, 2023 In this work, we characterize acoustic resonance phenomena occurring between gas bubbles in a segmented gas–liquid flow in a microchannel irradiated with a frequency around 500 kHz.

The spray characteristic of gas-liquid coaxial swirl injector by experiment
MATEC Web of Conferences, 2017 Using the laser phase Doppler particle analyzer (PDPA), the spray characteristics of gas-liquid coaxial swirl injector were studied. The Sauter mean diameter (SMD), axial velocity and size data rate were measured under different gas injecting pressure ...
