چکیده مقاله:
An experimental investigation was carried out to study convective heat transfer of nanofluid flow inside an inclined copper tube under uniform heat flux condition. Required data are acquired for laminar andhydrodynamically fully developed flow inside a round tube. The stable CuO-base oil nanofluid withdifferent nanoparticle weight fractions of 0.5%, 1% and 2% was produced by means of ultrasonic device in two steps method. In this study, the effect of different parameters such as tube inclination, nanofluid weight fraction and Reynolds number on heat transfer coefficient was considered. Results show that theheat transfer coefficient of nanofluid with different weight fractions increases with the increasing Reynolds number inside horizontal and inclined round tubes. Also, nanofluid flow inside the inclined tube at 30 degrees exhibit the most heat transfer enhancement amongst other tube inclinations at same Reynolds number.
