Abstract
The present paper gives an exclusive experimental coverage of the flas hing process of pure and gas-associated solutions of water at low abso lute pressures. The analyses include the phenomenon of bubble nucleati on, growth and departure from the source, and the consequential proper ties of the flashing and disintegration of the liquid jet. The influen ce of dissolvable substances in the liquid on the bubble nucleation an d altered liquid jet physical properties is also made clear. The outco me of the results also leads to the conclusion that, at high concentra tions of the solute gas, dissociative bubble nucleation dominates the process and is associated with simultaneous bubble nucleation at the s olid body-liquid interface and in the bulk of the liquid, especially a t low liquid temperatures.
