Summary

Numerical simulation of heat transfer to separation TiO2/water nanofluids flow in an asymmetric abrupt expansion was studied. The simulation used a computational fluid dynamics package (FLUENT) to investigate turbulent nanofluid flow in a horizontal double-tube heat exchanger. The results showed that increasing the Reynolds number increased the heat transfer coefficient and Nusselt number of the flowing fluid. The surface temperature dropped to its lowest value after the expansion and then gradually increased along the pipe. The chaotic movement and higher thermal conductivity of the TiO2 nanoparticles contributed to the overall heat transfer enhancement of the nanofluid compared to water.
