摘要：

Heat transfer rates to Newtonian fluids in a jacketed kettle using anchor agitators have been measured. Experimentally evaluated liquid‐film heat transfer coefficients at the vessel walls can be correlated by the modified Sieder‐Tate equation as used by previous workers but the results of the present and previous work are shown to be better correlated by the application of the theory of local isotropic turbulence. An attempt has also been made to establish the effect of wall clearance on the heat transfer efficiency of the contactor. The results indicate that high heat transfer rates obtainable with agitator‐scrapers can be realized with anchors without scrapers. Copyright © 1969 Canadian Society for Chemical Engineering
