Experimental Analysis on Annular Disc Heat Exchanger with Nano Fluids

In the present study a double pipe heat exchanger is fabricated with flow path modification in the annulus. The influence of nanoparticles on thermo-physical properties of the working fluid is evaluated using established correlations available in literature. The combined influence of copper oxide nanofluid on heat transfer is evaluated for two different volume concentrations of nanofluid. Two different volume concentrations of copper oxide nanofluid is prepared with water as the base fluid. The thermophysical properties are evaluated with established correlations available in literature. The fabricated test section is initially validated with water as the working fluid later experimentation is carried out using prepared two different volume concentrations of copper oxide nanofluid independently.
