“…Pedrosa and Nunhez (2003) showed that the design of vessels cooled by helical coils can be further improved by introducing some minor modifications in the coil arrangements. Triveni et al (2008) studied heat transfer of few industrially important systems namely castor oil and its methyl esters, soap solution, CMC and chalk slurries in a stirred vessel fitted with anchor/turbine impeller and a coil for heating or cooling. They investigated the effect of impeller geometry, speed and aeration.…”

Recommended Citation: Perarasu, V T; Arivazhagan, M; and Sivashanmugam, P (2011) "Heat Transfer Studies in Coiled AbstractHeat transfer studies in a coiled agitated vessel with varying heat input is presented using two agitators namely propeller and disk turbine. Heat transfer rate increases with agitator speed for both the agitators for a given heat input. The heat transfer coefficient also increases with heat input for a given agitator speed for turbine agitator for all the heat inputs, whereas for propeller it is increasing up to a certain value and then decreases. The heat transfer coefficient (heat transfer rate) for turbine agitator is higher than that for propeller for all heat inputs. Empirical correlations separately were formed for each agitator and found to fit the experimental values within range of ±15% for both the agitators.

“…Problems of heat transfer in agitated vessels, including theoretical backgrounds, methods of experiments and computations, as well as obtained results have been considered in detail in the following monographs [1][2][3] and papers [4][5][6] . The results of the mean heat transfer coefficient have been given in literature for different agitated liquids, for example: viscous fluids 7-10 , non-Newtonian fluids [10][11][12][13][14] and others [15][16] . The measurements of the local heat transfer coefficient have been also carried out for liquid [17][18][19][20][21] , gas-liquid [21][22][23][24][25][26] , solid-liquid 27 and gas-solid-liquid 28 systems.…”

The results of the experimental studies of the local heat transfer process for a gas-liquid system in the region of the cylindrical wall of baffled agitated vessel equipped with the system of A 315 (lower) -RT (upper) impellers are presented. Newtonian liquids of different physical properties and air were used as continuous and dispersed phases, respectively. Local heat transfer coefficients were measured using both thermal and electrochemical methods. Distributions of the heat transfer coefficients were described by means of equations (13) - (16) and (17) -(21), separately, for turbulent and transitional ranges of the fluid flow in the agitated vessel. These equations, concerning both coalescing and non-coalescing gas-liquid systems, have no equivalent in the open literature. Moreover, the results for the A 315 -RT impeller system were compared with our previous heat transfer data obtained using CD 6 -RT or RT -RT impeller systems.
