Bubble growth in superheated He II

Bubble Nucleation in Superheated Liquid-Liquid Emulsions

An investigation of the process by which bubbles form in superheated liquid-liquid emulsions is reported. A theoretical model for the rate of bubble nucleation is developed that is valid for any binary liquid system. Because of the interesting "microexplosion" phenomenon postulated to occur during combustion of fuel/water emulsions, special attention is focused on hydrocarbon/ water/surfactant ...

Growth of a Vapour Bubble in a Superheated Liquid of Variable Surface Tension and Viscosity Between Two-phase Flow

The growth of a vapour bubble in a superheated liquid of variable surface tension and viscosity between two finite boundaries is introduced. The problem is solved analytically using the modified method of Plesset and Zwick method. The pressure difference is described in terms of temperature difference and initial pressure difference. The surface tension, viscosity, and initial and final time of...

233401 - 1 Bubble Formation and Decay in 3 He and 4 He Clusters

The energy transfer in 3He and 4He clusters electronically excited by monochromatic synchrotron radiation is investigated by luminescence spectroscopy. Depending on the cluster size and the isotopic constitution, either sharp, broadened, or shifted emission bands of single He molecules are observed. The spectral features show that He molecules emit light either within a bubble inside the cluste...

Bubble growth in rhyolitic melt

We report experimental data of bubble growth in natural rhyolitic melt with 1.4^2.0 wt% initial total H2O at 0.1 MPa and 500^6003C. Growth of many bubbles is monitored in every experiment. Bubble growth rate increases with temperature and initial total H2O. At a given temperature and initial total H2O, bubble growth rate also increases slightly with bubble size. The average growth rate for bubb...
