Experimental Investigation Of Relative Performance Of Water Based Tio2 And Zno Nanofluids In A Double Pipe Heat Exchanger

This paper deals with experimental determination of convective heat transfer coefficient in a counter flow double pipe heat exchanger using water based TiO2, ZnO nanofluids with 0.002% & 0.004% volume concentrations. Experiments are conducted at various Reynolds numbers ranging from 1600 to 6100...
