Experimental study of heat transfer coefficient of nanofluid flow through a plain tube
description Heat transfer is one of the most important processes in many industrial. The inherently poor thermal performance of common fluids put a limitation and restricted in developing energy efficient heat transfer fluid. With a strong needed by industry in developing energy efficient, advance heat transfer fluid called nanofluid is introduced. Nanofluid is prepared by two step technique in this study by diluting Alumina nanoparticles with water at three different concentrations 0.02%, 0.10% and 0.50%. The heat transfer coefficient was investigated experimentally in a flow loop with a horizontal tube test section subjected to constant heat flux at a various flow rate ranges between Reynolds number 4,000 to 20,000.
