IILaminar flow heat transfer and pressure drop characteristics in a circular tube fitted with regularly spaced twisted-tape elements connected by thin circular rods were investigated experimentally. These characteristics are governed by Reynolds number, Prandtl number, twist ratio, space ratio, and
Experimental investigation of heat transfer and friction factor characteristics in a double pipe heat exchanger fitted with regularly spaced twisted tape elements, were studied. The inner and outer diameters of the inner tube are 50.6 and 25.8Β mm, respectively and cold and hot water were used as wor
Generalized correlations are evolved to predict friction factors and convective heat transfer coefficients with twisted tapes in a tube for a wide range of Reynolds numbers and Prandtl numbers. Satisfactory agreement between the present correlations and the data of others validate the proposed corre
