摘要：

In this study, laminar convective heat transfer for CuO/water nanofluid, which is a suspension of CuO nanoparticles in water, in a circular tube with the constant wall-temperature boundary condition was investigated experimentally. The heat-transfer coefficients for different volume fractions of solids at various Peclet numbers were determined experimentally. Also the viscosity of nanofluids was measured and compared with theoretical model predictions. Both theoretical and experimental results indicate that heat-transfer coefficients increase with nanoparticle concentration as well as the Peclet number. But the experimental results are greater than the values obtained by the homogeneous model with nanofluids physical and thermal properties.
