摘要：
Forced convective heat transfer studies have been carried out in an agitated shell and helical coil heat exchanger using CuO/water nanofluid. Experiments have been carried out in a shell and helical coil heat exchanger at various concentrations of CuO nanoparticles in water (0.3, 0.6, 1, 1.5 and 2% wt.), stirrer speeds (500, 1000 and 1500 rpm) and shell-side fluid (heating medium) temperatures (40, 45 and 50 degrees C). Water has been used as coil-side fluid, and studies have been conducted at different values of Dean number (flow rates). Enhancement in heat transfer due to the use of nanofluid has been reported in terms of heat transfer rate. (C) 2015 The Authors. Published by Elsevier Ltd.
