In the present study, the thermal performance of a finned tube heat exchanger using
aluminium oxidedeionized water nano-fluid has been evaluated. A counter flow type finned
tube heat exchanger has been selected for experimentation. The volume concentration of
aluminium oxide mixed with deionized water has been procured as 0.1, 0.2, 0.3, and 0.4% at
a temperature range of 10-90ºC. Stable nano-fluid dispersion is prepared with sodium
dodecylbenzene sulphonate and sodium hexametaphosphate which is used as a stabilizer …
