The results of the computational fluid dynamics model was analyzed in ANSYS CFD-Post and was then compared to the analytical data that was calculated using the Hamilton-Crosser equation. The Discrete Phase Model (DPM) has provided a reasonable prediction for calculating the Nusselt number and the convective heat transfer coefficient near the pipe exit. It was also noticed that the small nanoparticle concentrations had a negligible effect on enhancing both the thermal conductivity and the heat transfer performance of the nanofluid. These findings do not reflect those found in Wen and Ding’s experiment, which is what this numerical model is based on. However, these discrepancies could be due to a combination of experimental error and/or limitations in the Discrete Phase Model (DPM). Therefore, further study involving computational modeling of nanofluids by means of the Discrete Phase Model (DPM) is needed.
