ABSTRACT
IN THE PRESENT STUDY, THE HEAT TRANSFER BEHAVIOR OF COPPER NANOPARTICLE SUSPENDED WATER- ETHYLENE GLYCOL (50:50) BY VOLUME WAS EXPERIMENTALLY ANALYZED. IN ORDER TO ANALYZE THE HEAT TRANSFER BEHAVIOUR OF COPPER NANOPARTICLE, REYNOLDS NUMBER, PRANDTL NUMBER, NUSSELT NUMBER AND CONVECTIVE HEAT TRANSFER COEFFICIENT (H) WERE DETERMINED BY OBSERVING THE EFFECTS OF COPPER NANOPARTICLE VOLUME FRACTION (0.3, 0.6, 0.9, 1.2 AND 1.5%) AND HOT FLUID INLET TEMPERATURE (55°C, 65°C AND 75°C). FROM THE RESULTS IT WAS NOTED THAT THE REYNOLDS NUMBER AND NUSSELT NUMBER INCREASES WITH RESPECT TO THE HOT FLUID INLET TEMPERATURE AND NANOPARTICLE VOLUME FRACTION. THE PRANDTL NUMBER SHOWS DECREASING PATTERN, HOWEVER THE HEAT TRANSFER COEFFICIENT WAS INCREASED SIGNIFICANTLY BY THE ADDED NANOPARTICLE. THE OBTAINED RESULT INFERS THAT THE NANOPARTICLE HAS THE SIGNIFICANT CONTRIBUTION IN ENHANCING THE HEAT TRANSFER BEHAVIOR OF BASE FLUID.
