摘要：
In present study, an experimental investigation has been carried out to analyze the heat transfer characteristics of CuO- water nanofluids jets on a hot surface. A rectangular stainless steel foil (AISI-304, 0.15 mm thick) is used as a test surface is electrically heated to obtain the required initial temperature. The distribution of heat flux on the target surface is evaluated from the recorded thermal images during transient cooling. The effect of nanoparticle concentration and Reynolds number of the nanofluids jet impingement heat transfer characteristics is studied. Tests were performed for an initial surface temperature of 500 degrees C, Reynolds number (5000 <= Re <= 13000), CuO-water nanofluids concentration Phi = 0.15%, 0.6%) and nozzle to plate distance was l/d=4.
