Phase Transitional Flow

Unit operations in the process industry often involve flows with change of phase, mostly in conjunction with exchange of heat. This is particularly true for the novel technological equipment developed within the section. The research addresses basic phenomena of boiling and bubble detachment, of dropwise condensation, of particle motion and phase distributions and of the formation and coagulation of particles in heat exchangers.
