crane-driving, and it is probable that improvements in single and two-phase motors will eventually largely increase their use for this class of work.
The ordinary surface energy of a two-phase system tends to diminish the area of contact, and thus to help the growth of the larger aggregates required for coagulation.
hysteresis effects were represented by empirical models based on two-phase flow.
Theoretical models of shell and tube boilers suitable for boiling two-phase mixtures are under development.
two-phase flow in pipe line systems has been initiated.
