MODELLING OF CONVECTIVE HEAT EXCHANGE AT PHASE INTERFACE OF ELECTROLYTE - WALL IN ALUMINIUM ELECTROLYZER

There the heat exchange processes, which were complicated by the crystallization on the cooled wall, and the processes without the crystallization during the laminar flow of model electrlyte. The purpose is to learn the mechanisms of influence of hydrodynamical conditions and of cooling modes on the rate of heat exchange. The conditions of high-rate formation of protective crystal layer on the carbon-graphite lining of aluminium electrolyzer at the diverse recycling rates of model electrolyte and under the diverse temperature conditions of cooling have been modelled and have been learned. The electrolyzer to make the metals and the alloys, the manner of control over the flow rate of hostile fluids have been developed on the basis of study. The comprehensive manner to learn the heat exchange processes in the analogous systems in use in practice is the introduction subject. The results of executed study may be used to obtain the operating characteristics of cooling plants in use to control over the garnissage thickness in the pyrometallurgical assemblies. The application fields are the chemical, petrochemical and metallurgical industriesAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
