ABSTRACT In the paper, the problems of heat transport in the agitated vessels, equipped with a jacket or a coil, have been analysed on the basis of our own and literature results of the studies. Different methods of the measurement of mean and local heat transfer coefficients have been described. Thermal (direct) and an electrochemical (indirect) measuring methods have been taken into account. Recent results of the experimental studies of the heat transfer coefficients in agitated vessels of different geometry have been collected and compared. The effects of the type of the agitators and baffles, as well as, the configuration of the heat transfer process have been analysed. The results of our experimental studies obtained for novel impellers (CD6,HE3,A315, INTERMIG), as well as, for vertical coils of original project have been quoted. The data for single liquid system and gas-liquid, solid-liquid or gas – solid – liquid systems have been presented. Mathematical modeling of local heat transfer at the vicinity of the agitated vessel wall has been considered. Analytically solved, theoretical equation obtained for two-dimensional turbulent boundary layer, has been proposed. The problems of the numerical modeling of local heat transfer coefficients in agitated vessels have also been undertaken and analysed.
