摘要
本文研究了层流域MIG桨搅拌的传热性能。实测了搅拌功率。获得了计算四层及七层MIG桨搅拌槽内壁传热膜系数的准数关联式,它们可作为工程设计的依据。并对四层及七层MIG桨性能进行了综合评价。
The heat transfer characteristics of laminar flow region in an agitated vessel with MIG imperller were studied. The power consumption for the MIG impeller were measured. Nondimensional correlations of heat transfer film coefficients at the inside of an agitated vessel with seven-stage and four-stage MIG impellers were obtained respetively for designing purposes. A comprehensive appraisal of the two kinds of impeller is given.
