ABSTRACT

The physical and thermodynamical aspects of the principle of discrete and pulse input of energy (DPIE) as a new approach to intensification of heat and mass transfer and hydrodynamic processes in multiphase liquid systems are considered. The intensification effects are shown to be connected to the dynamical action of bubbles which are distributed within the liquid and can grow or collapse intensively when the ambient pressure changes rapidly. The possible mechanisms of intensification are discussed as well as the main conditions of their efficiency. A comprehensive theoretical and experimental investigation of the DPIE mechanisms has resulted in the creation of a new class of mass exchanging devices and efficient dispersers which are successfully used now in various industries. While all of these devices are comparable to conventional equipment used for this purpose, they are of simple design, high reliability in operation and small dimensions. The DPIE methods appear to be quite promising when applied to the development of innovative efficient technologies and advanced production processes that can enable to save power and resources.
