Experimental studies on flow and heat transfer characteristics of secondary refrigerant-based CNT nanofluids for cooling applications

The aim of the research work is explore the convective heat transfer coefficient characteristics of propanol based nano fluids for cooling applications. The stable suspension of the nano fluid with volume fraction of 0.15 and 0.3 are prepared and characterized. The measurement on the density shows that there is only negligible increase in the density of the nano fluid and the specific heat of the nano fluid increases with volumetric concentration of nano fluids. Further there is an enhancement in the convective heat transfer coefficient of 70% for the nano fluid containing
0.3% of CNT.
