Satellite-particle control technique based on gas-flow-regulation during gas atomization process [PDF]

open access: yesFenmo yejin jishu, 2022
Gas atomization (GA) is an essential method for the preparation of metal powders specifically used in the additive manufacturing. However, there are plenty of “satellites” among the metal powders prepared by GA. The existence of these satellite particles

Precise control of atomization initial stage to address nozzle clogging issue in the vacuum induction-melting gas atomization process

open access: yesJournal of Materials Research and Technology
Vacuum induction-melting gas atomization (VIGA) is considered a widely applied method to prepare metal powders. However, the nozzle clogging problem in the VIGA process seriously affects the continuity of production and greatly increases the economic and

Flash Atomization: A New Concept to Control Combustion Instability in Water-Injected Gas Turbines [PDF]

open access: yesJournal of Combustion, 2012
The objective of this work is to explore methods to reduce combustor rumble in a water-injected gas turbine. Attempts to use water injection as a means to reduce NOX emissions in gas turbines have been largely unsuccessful because of increased combustion

Effect of melt tip taper angle on atomization process in gas atomization [PDF]

open access: yesFenmo yejin jishu
Atomizing nozzle is the core component of the gas atomization process, which structural parameters, especially the melt tip taper angle of the delivery tube, have the great impact on the gas atomization results.

Improving gas flow in gas atomization

open access: yes, 2021
Gasatomisering är en kostnadseffektiv metod för att tillverka fint, sfäriskt metallpulver. Processen går till så att gas med väldigt hög hastighet sprayas mot en stråle med smält metall. Metallstrålen bryts upp i små, små droppar som stelnar och bildar pulverpartiklar.

Performance Testing and Rapid Solidification Behavior of Stainless Steel Powders Prepared by Gas Atomization. [PDF]

open access: yesMaterials (Basel), 2021
Gas atomization is a widely used method to produce the raw powder materials for additive manufacturing (AM) usage. After the metal alloy is melted to fusion, gas atomization involves two relatively independent processes: liquid breakup and droplet ...

Atomic hydrogen: the quantum gas [PDF]

open access: yesPhysics 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 ...
