Simulation of the coalescence and breakup of water-in-oil …

The device utilizes an electric field to coalesce droplets, meanwhile a swirling centrifugal field is used to realize the rapid separation of water from oil. The coalescence and breakup of droplets in emulsified oil, which are dynamic and complicated processes, directly influence the separation effect of the device.

Fractional crystallization of high-K arc magmas: biotite

Field relationships clearly indicate that quartz–monzonites that have biotite as the predominant hydrous mineral are intimately related to the biotite-dominated cumulate sequence (Bucholz et al. 2014). Therefore, in order to test whether these evolved quartz–monzonites and late-stage felsic dikes could be produced by fractionation of the ...

(PDF) Magnetism of biotite crystals

Within the biotite field, biotite exists with different degrees of oxidation, depending on the oxygen fugacity within the single-phase region. In addition, during T–fO2 excursions outside the original single-phase biotite field, conditions can become more oxidizing too quickly (as a result of decreasing T, for example) for the resulting ...

Centrifugal Force: Definition, Examples, and Equation

Centrifugal force is an apparent force experienced by an object going around a curve or circular path. It is an outward force felt by the object in its frame of reference and directed away from the center of curvature. It is opposite to the centripetal force but not a reaction of the latter. Is Centrifugal Force Real.

A fundamental theory based on the local momentum balances is proposed to explore the fluidizing phenomena of a centrifugal particle bed. Unlike the conventional vertical bed, a centrifugal bed is predicted to be fluidized layer by layer from the inner free surface outward, in a range of aeration rates. The span of this range increases with the ...
