Heat transfer characteristics of two-phase slug flow without phase change in a 600 μm tube are examined Since the contribution of the gas phase on heat transfer is negligibly small, we focus on the effects of the Reynolds number, and slug length on the Nusselt number inside liquid slug. It is found that the Nusselt number in liquid slug is independent of the Reynolds number, and increases with decreasing the slug length. These trends agree fairly well with previous numerical results. The present results suggest that the two-phase flow has a potential to achieve around 4 times larger heat transfer rate than single-phase flow, while heat transfer per unit pumping power is kept almost unchanged.
