AB - In this study, the effect of various concentrations of Al2O3-water nanofluid  on heat transfer in duct with a square cross-section, under conditions of  continuous heat flux and laminar forced flow, investigated numerically.  Reference experi-mental application parameters are accepted as reference,  calculated with single phase homogeneous model (SPHM) and single phase  Brownian model (SPBM) models, and the average heat transfer coefficient  results of numerical models are compared with each other and reference  experimental data. Numerical results obtained with SPHM and SPBM are in  comparison to the relevant experimental data. For SPHM and SPBM results,  0.5%, %1.5, %2.5 Al2O3-water nanofluids, the average deviation rate for the  average heat transfer coefficient is 3.35% and 2.36%, 5.24%, 3.43%, 7.74%,  and 5.3% according to the reference experimental data respectively. 0.5%,  %1.5, %2.5, 2.24%, and 3.81%, 5.86% and 7.47%, 9.58% and 11.6%,  respectively, the average heat transfer coefficient is increased by using  Al2O3-water nanofluid compared to water. It has been observed that, SPBM has  closer results than SPHM model according the relevant experimental data.
