HEAT TRANSFER ENHANCEMENT IN MINI COMPACT HEAT EXCHANGER BY USING ALUMINA NANOFLUID

In the recent research activities, the nanofluids have involved a great deal attention since their superior report in thermal performance and many other applications. Now a days cooling process is a great challe ge in most of the chemical process, Nuclear reactor, automobile radiator, micro electronics systems. To meet out this, a novel coolant (Nano fluids) was developed by choi.S.U.S 1995 at Argonne
National lab. USA. In continuation to his work, water based alumina Nano fluids was prepared and applied in shell and tube heat exchanger to analyze the heat transfer rate. The same analysis is discussed with conventional base fluid of water and alumina nanofluid also this presents the characterization of Alumina Nano particle by means of XRD and SEM.
