Experimental investigation of explosive vaporization of C6F14

Abstract : Depressurization experiments were conducted with C6F14 for superheats between 5°C and 90°C in order to determine how the drop characteristics evolve with the thermodynamic disequilibrium. High-speed imaging indicates that flashing is predominant and leads to very dense sprays. Phase Doppler Interferometer was adapted to these optically thick conditions and its ability to provide unbiased velocity and size distributions was carefully checked (even though the flux was underestimated). Experiments show that, for initial superheats above 40°C, the mean drop velocity linearly increases with the initial superheat while the mean drop diameter remains nearly constant. The significance of these findings is discussed.
