Abstract
Nanofluids are employed as the working medium for a conventional cylindrical heat pipe A cylindrical copper heat pipe of 195 mm outer diameter and 400 mm length was fabricated and tested with two different working fluids The working fluids used in this study are DIwater and Nanoparticles suspension mixture of copper nano particle and DIwater The overall heat transfer coefficient of the heat pipe was calculated based on the lumped thermal resistance network and compared with the heat transfer coefficient of base fluid filled heat pipe There is a quantitative improvement in the heat transfer coefficient using nanoparticles suspension as the working medium A heat transfer correlation was also developed based on multiple regression least square method and the results were compared with that obtained by the experiment
