An Experimental Procedure to Investigate the Thermal Conductivity of Various types of Nanofluids

Abstract

In this experimental research work, thermal conductivity of disparate types of nanofluid samples was investigated. Nanofluid has ability for enhancement in heat transfer due to their high value of thermal conductivity. KD2 Pro instrument was used to measure the thermal conductivity, which is hinged on transient hot wire mechanism. Dissimilar nanofluids like MWCNT-H2O, Al2O3-H2O, and Al2O3-H2O-C2H6O were fabricated with divergent volume concentration. Thermal conductivity was measured at unlike temperature by setting up the KD2 Pro at an automated mode for time interval of 15 minutes. Experimental findings showed that MWCNT- H2O based nanofluid with 0.02wt% possess higher value of thermal conductivity among conventional and other nanofluids with different concentrations.
