B211 超音速空気流れによる水の微粒化と冷却現象(融解・凝固)
詳細
The ice nucleation of water atomized by supersonic air streams was investigated through the experiment with a phase Doppler particle analyzer and the unsteady thermal conductive analysis. The experimental results show that the average diameter and velocity of the water droplets are 8μm and 484m/s respectively at the nozzle exit. The thermal conductive analyses indicate that the water droplet which diameter is smaller than 5μm freezes inside the nozzle regardless the relative velocity for the air streams.
