چکیده
|
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.
