HEAT EXCHANGE AT CONDENSATION OF STEAM FROM MIXTURE WITH AIR ON VERTICAL PIPES AND BEAMS IN CLOSED VOLUME IN HEAT-EXCHANGE DEVICES OF NUCLEAR POWER PLANT (NPP)

Abstract

The steam condensation process from vapour-gas mixture on the vertical surfaces in the closed systems of the NPP heat heat-exchange devices is investigated. The different mathematical models have been developed. The experimental investigation of the heat emission at condensation of the steam from mixture with air on the vertical pipes and beams has been performed. The shielding effect in the beams has been substantiated theoretically and has been confirmed in experiment. The recommendations on design of the heat emission at steam condensation from mixture with air on the vertical pipes and beams have been givenAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
