Abstract

An experimental investigation is carried out to determine the effect of concentration (up to 2 % by volume) of water based Al2O3 as a nano fluid tube on heat transfer characteristics of shell and tube heat exchanger. The laminar flow based results with 2 % concentration showed an increase in heat transfer rate of 34 %, 44.8 % and 57.6 % for the shell side flow rate of 2 lpm, 3 lpm , 4 lpm and tube side flow rate of 1 lpm, 2 lpm, 3 lpm respectively. For different flow rate of fluids at shell and tube side, the various energy parameters attained maximum values at concentration of 2 %. This upward trend being continue till the viscous force dominates in the flow path. If turbulence is created by adding inserts in the flow path, further rise in heat transfer rate is possible with higher percentage of nano fluid concentration at the cost of pressure drop
