Laminar Flow Heat Transfer of a Pseudoplastic Fluid through a Double Pipe Heat Exchanger %K Non-Newtonian Fluids %K Double-pipe Heat Exchanger %K Nusselt Number %K Greatz Number %K experimental %R %X 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. %U https://www.ijche.com/article_15212_f7766fd458e62857b922ce5582917252.pdf
