Abstract:
The heat transfer behavior of liquid-liquid two-phase Taylor flow in a microchannel with a square cross section is studied experimentally. The microchannel is heated with a constant heat flux boundary condition. Kerosene and water were used as working fluids. The effect of varying void fraction, slug length and droplet length on the heat transfer rate of the liquid-liquid Taylor flow are investigated. The results indicate that liquid-liquid two-phase Taylor flow can increase the rate of heat transfer by up to 700% compared to single phase flow. The droplet and slug lengths are found to have a significant effect on the heat transfer rate for liquid-liquid twophase flow in microchannels.
