Heat transfer in a jacketed agitated vessel equipped with multistage impellers

Popis výsledku v původním jazyce

In this work, heat transfer via the cylindrical part of the jacket in an agitated vessel has been investigated. Heat transfer coefficients were determined using the transient method based on measuring the temperature dependency of the liquid batch on time. A multistage impeller made of two impellers was used in a cylindrical vessel with dished bottom. The lower impeller was a curved blade turbine with the diameter of d = 100 mm and the upper impeller was either a pitched three-blade or pitched four-blade impeller with the diameter of d1 = 67 mm. Three different impeller clearances in a multistage configuration, H3/d1 = 1, 1.5, and 2, were used in our measurements. The vessel was equipped with two baffles. Experimental results were evaluated using the Euler?s method and nonlinear regression procedure in the Matlab? software and they are summarized in form of Nusselt number correlations describing their dependency on the Reynolds number.
