Liquids in Jacketed or Coiled Vessels

Many correlations are available for heat transfer between liquids and the walls of stirred vessels or the surface of coiled tubes installed in the stirred vessels. For details of the different types of stirrer available, see Section 7.4.1. 

Data on heat transfer between liquid and the vessel wall and between liquid and the surface of helical coil in the vessels stirred with flat-blade paddle stirrers were correlated as [4]  

Data on heat transfer between a liquid and the wall of vessel of diameter D, stirred by a vaned-disk turbine, were correlated [5] by Equation 5.13. The values of a were 0.54 without baffles, and 0.74 with baffles.
