The number of computational cells assigned to a small bubble is liable to be small in a volume tracking simulation of a poly-dispersed bubbly flow. The volume tracking method is, therefore, expected to at least give qualitatively reasonable predictions of bubble motion without assigning many cells. In this study, bubble motions in stagnant water and shear flows are simulated with low spatial re...

[1] The bubble cloud depth and its correlation with extreme winds are key elements of bubble‐mediated gas injection, which are critical to the determination of the global gas budgets. The characteristics of bubble cloud depth were examined frommeasurements collected during the passage of a category‐4 hurricane with winds up to 50 m s. The bubble cloud depth increases linearly with wind speed fo...

Joule heat generated by resistive elements of cryogenic micro- and nanodevices often originates boiling the cooling liquids (helium, nitrogen). The article proposes an experimental method to explore dynamics formation development a single vapor bubble in liquid sensing temperature change superconducting thin-film microbridge being state with phase slip center or line. It serves both source for ...

We study the topology and geometry of two-dimensional coarsening foam with an arbitrary liquid fraction. To interpolate between the dry limit described by von Neumann's law and the wet limit described by Marqusee's equation, the relevant bubble characteristics are the Plateau border radius and a new variable: the effective number of sides. We propose an equation for the individual bubble growth...

An experimental study of saturated pool boiling from a single artificial nucleation site on a polished copper surface has been performed. Isolated bubbles grow and depart from the artificial cavity and the bubble dynamics are recorded with a high speed camera. Experimental results are obtained for bubble growth, departure and vertical rise both with and without the application of an electric fi...
