The present paper focuses on the heat transfer of an equilateral triangular duct by employing the CuO/water nanofluid in laminar flow and under constant heat flux condition. The triangular ducts due to their easy forming and high compaction and less pressure drop compared to the circular and non-circular ones and other their abilities are very useful in industrial applications. This reasons cause that their heat transfer improving be very important. In this paper, to improve the heat transfer of an equilateral triangular duct, a CuO/water nanofluid was employed. The nanofluid was conducted through an equilateral triangular duct with a constant wall heat flux. Results show that the experimental heat transfer coefficient of the CuO/water nanofluid is more than that of distillated water. Also, the experimental heat transfer coefficient of CuO/water nanofluid is greater than the theoretical one. The heat transfer enhancement of the equilateral triangular duct increases with the nanofluid volume concentration as well as the Peclet number. So, a 41% enhancement in the convective heat transfer coefficient for a 0.8% CuO/water nanofluid can be seen when compared to pure water.
