Abstract

Two-phase flows of water and water vapour (liquid and gas) are very frequent in thermal energy systems where evaporation or condensation processes take place. The intensity of many technological processes depends on the inter-contact surface size of both phases (liquid and gas). Foam is distinguished by especially large inter-phase contact surface and can be applied for the conduction of different purpose heat and mass exchanges. Apparatus with foam flow are suitable for use in different technologies like heat exchangers, the food industry, and the chemical and oil processing industry. Statically stable liquid foam until now has been used in technologic systems rather seldom, although the usage of this type of foam as a heat transfer agent in foam equipment has a number of advantages in comparison with one
