Effect of dissolved gas on bubble nucleation

Experiments studying the extinction of a gas bubble in a liquid droplet and the possibility of bubble formation in a droplet containing dissolved gas are used to investigate the effect of dissolved gas on liquid-gas phase transitions (boiling, caviation, etc.). The superheat limit of the liquid was studied using a technique in which a droplet containing a dissolved gas was suspended in an immiscible fluid medium. Results show that with an increase of dissolved gas content, homogeneous nucleation occurs at lower temperatures and in the presence of a dissolved gas at pressures above the saturation pressure of the pure solvent.
