Atomization mode

Most commercial and near-commercial atomization processes for liquid metals/alloys involve two-fluid atomization or centrifugal atomization. As suggested by many experimental observations, two-fluid atomization of liquid metals is typically a three-stage process, 3IX 3 yl whereas centrifugal atomization may occur in three different regimes.[5][320] Many atomization modes and mechanisms for normal liquids may be adopted or directly employed to account... 

In both atomization modes, as thin unstable ligaments, and/ or sheets disintegrate into round droplets, atomization gas may plausibly be trapped into the droplets under certain conditions. For alloys with alloying elements which readily react with atomization gas, for example, oxidize to form refractory oxides, solidification may be delayed and spheroidization is prevented so that rough flakes may form. For such alloys, the atmosphere in the spray chamber must be inert and protective to avoid the formation of any refractory and to foster spheroidal shape of droplets. 

Droplet Formation in Centrifugal Atomization. The mechanisms of centrifugal atomization of liquid metals are quite similar to those for normal liquids. Three atomization modes have been identified in rotating electrode atomization process, i.e., (I) Direct Droplet Formation, (2) Ligament Disintegration, and (3) Film/Sheet Disintegration.1[189][32°] are aiso applicable to the centrifugal atomiza-... 

The calculations are best made following the strategy explained for the dienes, in the atom-by-atom mode. 

Note The coordination of TIME in [CufTIMEI- )J(PFJ is indeed [2+1] with the mon-odentate end coordinating in abnormal (with the O-atom) mode. 

Coordination of urea to a single Ni(II) ion via its O atom (mode D) does not appreciably alter the structural parameters of the carbonyl group and causes only a moderate shift of v(CO) from 1683 cm (121) to 1640-1660 cm This result suggests that the substrate is poorly activated in this binding mode. Nevertheless, the two C—N bonds may become significantly different in the bound substrate. 

It is generally believed that crystal growth in solution occurs via an Ostwald-ripening mechanism (see above). Normally, this is assumed to proceed via addition of monomers to a polymer (cluster, nanocrystal, crystal). However, as noted above and described in more detail below and by Waychunas (this volume), this atom-by-atom mode of crystal growth is not unique, especially in nanomaterials. 

RDF. The distance mode dehnes the mode for distance calculation available modes are Cartesian distances, bond-path distances, and topological distances. Descriptors may be calculated on particular atoms. Exclusive mode restricts the calculation to the atom type, and with ignore mode the selected atom type is ignored when calculating the descriptor. In partial-atom mode an atom number has to be given instead of the atom type. The second atom property is available if 2D RDF is selected as code method. 

We would like to remark here that the implications of Eq. (20b) are consistent with the familiar superposition principle of quantum mechanics. Namely, as shown in the next section, the Hilbert space interpretation of 11 = , as expansion coefficient of the normal mode a> in terms of the atomic modes f>. 

Can it be applied to fluids with complex rheology or different atomization modes Unknown. Unclear whether it would be possible to formulate the appropriate constraints for complex liquids Yes Yes... 

In such a cavity, the transverse (horizontal) size of the atomic mode can be expressed in terms of the distance L from the surface of the mirror to the classical turning point, which determines the length of the cavity. For estimation purposes, the gradient force potential can be taken to be stepped near the surface of the mirror. The shape of the surface of the mirror in the simplest approximation can he treated as a paraboloid of revolution,... 

The distance to the upper point of the classical trajectory is determined by the atomic velocity in the neighborhood of the mirror, L = v /2g, and can be associated with the energy of longitudinal motion given by eqn (6.10). With the typical gravitational length being, as indicated above, of the order of a micron, the size of the atom mode is a few tens of microns. 

Not only thermodynamic parameters such as pressure and temperature hut also hydrodynamic parameters such as nozzle diameter and liquid solution flow rate of both polymers were investigated using the SAS process. In order to achieve successful precipitation of polymer nano- and microparticles from a single supercritical phase, the experimental conditions (pressure and temperature] should be far above the mixture critical point (MCP] of CO2 and solvent. Anyway, the appropriate nozzle diameter and jet velocity should be used in order to ensure an atomization mode near to, or slightly above, this mixture critical point. The jet breakup time should be higher than the time for the disappearance of the interface between the liquid and the fluid phase.
