A Study of Liquid Metal Atomization Using Close-Coupled Nozzles, Part 1: Gas Dynamic Behavior

Log-Normal Melt Pulsation in Close-Coupled Gas Atomization

“…Once reestablished melt is again able to flow into the recirculation zone and the cycle is re-established. However this is disputed by Mates and Settles [8,9] who suggest that wake closure is of no real consequence in atomization as the closed-wake structure is not preserved during the actual atomization process.…”

Breakup Morphology and Mechanisms of Liquid Atomization

“…Viscoelasticity increases the mean drop diameter and broadens the size distribution. Liquids with atypical properties, such as gels, liquid metal, and strain-thickening liquids, are also studied widely [139][140][141][142][143][144][145][146][147].…”

Gas atomized precursor alloy powder for oxide dispersion strengthened ferritic stainless steel

“…Equation 38 Equation 39 The velocity profile of the atomization gas was assumed to follow the decay function described by Alam et al (Equation 40), which was found to be dependent on the effective diameter (de) of the gas nozzle [150,151].…”

“…Where, η=0.0841 and χ=0.06035 [150] de=center bore of atomization nozzle [151] The initial velocity (i.e., after the first time interval) of the as-atomized droplets was calculated using Bernoulli's equation (see Equation 41 and Equation 42) [152], and the effects of aspiration were disregarded. Additionally, it was assumed that the molten alloy exits the pour tube as a predefined volumetric distribution of spherical droplets, thus neglecting the time required for droplet formation.…”
