Moradi Department of Chemical Engineering, Isfahan University of Technology, Isfahan, Iran. S. Gh. Etemad Department of Chemical Engineering, Isfahan University of Technology, Isfahan, Iran A. Moheb Journal Article 2016 05 30 An experimental study was carried out to obtain the mean convective heat transfer coefficient of aqueous carboximethyl cellulose (CMC) solutions in double-pipe heat exchangers. Co-current and counter- flows were considered in the investigation. From the experimental data a Nusselt number was calculated for a wide range of Graetz number, Reynolds number, and CMC concentrations. Increasing the Graetz and Reynolds numbers promote the heat transfer and variation of CMC concentration has a noticeable effect on the Nusselt number.
