Laminar Flow Heat Transfer of a Pseudoplastic Fluid through a Double Pipe Heat Exchanger

Abstract

<span style="font-size: 10pt; color: #000000; font-style: normal; font-variant: normal;"><em>An experimental study was carried out to obtain the mean convective heat transfer</em> <span style="font-size: 10pt; color: #000000; font-style: normal; font-variant: normal;"><em>coefficient of aqueous carboximethyl cellulose (CMC) solutions in double-pipe heat</em> <span style="font-size: 10pt; color: #000000; font-style: normal; font-variant: normal;"><em>exchangers. Co-current and counter- flows were considered in the investigation. From</em> <span style="font-size: 10pt; color: #000000; font-style: normal; font-variant: normal;"><em>the experimental data a Nusselt number was calculated for a wide range of Graetz</em> <span style="font-size: 10pt; color: #000000; font-style: normal; font-variant: normal;"><em>number, Reynolds number, and CMC concentrations. Increasing the Graetz and</em> <span style="font-size: 10pt; color: #000000; font-style: normal; font-variant: normal;"><em>Reynolds numbers promote the heat transfer and variation of CMC concentration has</em> <span style="font-size: 10pt; color: #000000; font-style: normal; font-variant: normal;"><em>a noticeable effect on the Nusselt number.</em> </span></span></span></span></span><br class="Apple-interchange-newline" /></span></span>
