VIBRATING PROCESSES IN TWO-PHASE MEDIA AND THEIR INFLUENCE ON HEAT-AND MASS EXCHANGE

The work covers the vibrating processes in two-phase media. The aim of the work is to investigate the gas-liquid flows in the pipe at extrernal cross vibrations and at pulsations of the flow rate and also to investigate the dynamic processes in two-phase media in the closed capacities. The diagnostic methods of gas-liquid flows at presence of the vibrations and flow rate pulsations have been developed, the influence of the temperature and physical liquid properties on the vibration mixing has been investigated experimentally. The data about influence of the external cross vibrations and flow rate pulsations on the hydrodynamic parameters at flow of the gas-liquid flows in pipe have been obtained firstly. The efficiency of applying wave technology for the intensification of a number of the typical technolofical processes in the closed capacities and pipe-line systems has been substantiated experimentally. The new criterion correlations for design of the critical conditions have been obtained. The recommendations on the modelling of the bubble boiling by a splashing lubrication have been developed, the technical material taking influence of the vibrations and flow rate in the heat-transfer agent on the heat-physical reliability and critical power of the heat-generating assemblies in the RBMK type reactor into consideration hzve been proposedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
