The fate of bubbles formed in tissues during decompression to altitude after diving or due to accidental loss of cabin pressure during flight has only been indirectly inferred from theoretical modeling and clinical observations with noninvasive bubble-measuring techniques of intravascular bubbles. In this report we visually followed the in vivo resolution of micro-air bubbles injected into adip...
We present general properties of ionized hydrogen (HII) bubbles and their growth based on a stateof-the-art large-scale (100 Mpc/h) cosmological radiative transfer simulation. The simulation resolves all halos with atomic cooling at the relevant redshifts and simultaneously performs radiative transfer and dynamical evolution of structure formation. Our major conclusions include: (1) for signifi...
The dynamics of single vapor bubbles in FC-72 generated by a transient heat pulse applied to a square 260 · 260 lm microheater are investigated for different heat fluxes between 3 and 44 MW/m. It is found that in all cases the growth consists of two steps, a first relatively violent one, followed by a shrinking of the vapor mass and a subsequent slower expansion. At the higher heat fluxes, the ...
in this research, the effect of bubble surface area flux, sb, and particle size on flotation rate constant, k, of pyrite (fes2) particles was studied using bubble-particle interactions. the bubble-particle collision, attachment and detachment efficiencies were calculated under different flow regimes. the k increased with increase in the collision efficiency and decrease in the detachment effici...
Moving single bubble sonoluminescence has been discovered after searches to find the fluids other than water for observing SBSL. The main property of these fluids is their more viscosity rather than water. In this paper, after introducing the forces which act on sonoluminescing bubble, the moving of the bubble have been simulated. For this purpose, the bubble’s equation of motion is coupled w...
Hadron bubbles that nucleate with radius Rnuc in a quark sea (if the phase transition is first order) are shown to be unstable to the growth of nonspherical structure when the bubble radii exceed a critical size of 20−10 Rnuc. This instability is driven by a very thin layer of slowly diffusing excess baryon number that forms on the surface of the bubble wall and limits its growth. This instabil...
