  • Owing to the factors influencing microchannel heat transfer behavior are complicated, the experimental results were contrary each other. The combination of experiment and numerical simulation has become a valid method to get deep understood of the heat transfer characteristics. On the basis of experimental research, heat transfer characteristic of 30% (volume concentration) ethanol solution in rectangle microchannels was numerically simulated. Two different symmetry structures and thermal boundary conditions of microchannels were used. The fully developed boundary conditions were adopted for the inlet fluid boundary. The results of two different symmetry structures with constant fluid thermal property and that changed with temperature were compared. The results were compared with experimental results as well. It shows that simulation and experimental results are fit well to the microchannels and the work fluid used here with fully developed flow inlet condition and thermal property changed with temperature.
