Heat Transfer in Stirred Vessel with SCFs

Heat Transfer in Stirred Vessel with SCFs 

The general equation for heat transfer across an interface is 

To correlate internal mixing with heat transfer, the Nusselt number (Nu=h dj l) of the reactor is related to the Reynolds (Re=pNds/fi) and Prandtl Pr=juCp/l) number according to 

Combining Eqs. (6) and (8) then yields Eq. (9), in which the overall heat transfer resistance is coupled to the stirrer speed N  

The slope of the regression lines allows calculation of the internal film transfer coefficient. From the intercept with the U axis the external part of the overall heat transfer coefficient can be determined. As the regression Hnes intercept be-
