| Research Abstract |
Enhancement of heat transfer by use of nano-slurry has been investigated experimentally. Thermal properties of water-based 10wt% Al_2O_3 nano-slurry were measured firstly. The slurry showed 7% higher thermal conductivity than that of the water. Heat transfer by the forced convection from the heated pipe to the nano-slurry was subsequently measured. The result showed that the Nusselt numbers are almost the same between the nano-slurry and water. The identical result was also obtained for the heat transfer by the impinging jet of nano-slurry and water.
