Experimental Observation of Liquid Exploding Emissionin Micro Tubes

摘要：

In present paper, a high speed CCD was employed to conduct a visualized observation of the phenomena of nucleation in micro capillary tubes covered with transparent metal film on the tube serving as the heater. When the heat flux reached a certain value, the liquid in capillary tubes was emitted instantaneously, which is referred as liquid exploding emission here, rather than generating visible bubbles. The critical heat flux and tube inner temperature corresponding to this phenomenon were measured to discuss the fundamental characteristics and physical significance of the phenomenon in ifferent capillary tubes having different tube length, heating length and diameters.
