ANALYSIS ON FLOW AND HEAT TRANSFER PERFORMANCE OF CUO NANO-FLUID

_______________________________________________________________________________________ Abstract Heat exchangers are widely used in the heat transfer applications where heat to be rejected or inserted by the system or in to the system. Since past few decades, researchers have found that the rate of heat transfer can be enhance during nano-fluids as they are having better thermophysical properties compared to conventional fluids. Using Two-Step Method, a nano-fluid has been prepared by adding CuO particles into distilled water. The arrangement has been done in such a way that the hot fluid (hot water and nano-fluid) flows through inner pipe and cold water is flowing through the outer pipe. It was detected that the convective heat transfer has improved when CuO-H 2 O nanofluid was used instead of water.
