Abstrakt: The heat-transfer coefficient in a divergent–convergent tubular apparatus is 1.4–1.7 times larger than that in a cylindrical apparatus, the specific output of the divergent–convergent tubular apparatus is 1.3–1.4 times higher than that of the cylindrical apparatus, and the residence time of a reaction mixture (or a heat-transfer medium) in the heat-transfer zone of the divergent–convergent tubular apparatus is 1.8 times shorter than that of the cylindrical apparatus. A relationship is revealed between the heat-transfer coefficient and the liquid flow pattern. [ABSTRACT FROM AUTHOR]
