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.
