Rise velocity of a spherical cap bubble By DANIEL
where R = D/2 is the radius of the cap, ρ and ν are the density and kinematic viscosity of the liquid, σ is surface tension, r(θ) = R(1 + sθ) and s = r ′′(0)/D is the deviation of the free surface from perfect sphericity r(θ) = R near the stagnation point θ = 0. The bubble nose is more pointed when s < 0 and blunted when s > 0. A more pointed bubble increases the rise velocity; the blunter bubb...
متن کاملCombining spherical-cap and Taylor bubble fluid
Basaltic activity is the most common class of volcanism on Earth, characterized by magmas 12 of sufficiently low viscosities such that bubbles can move independently of the melt. Following 13 exsolution, spherical bubbles can then expand and/or coalesce to generate larger bubbles of 14 spherical-cap or Taylor bubble (slug) morphologies. Puffing and strombolian explosive activity are 15 driven b...
متن کاملUWFDM-1301 Shock-Induced Instabilities on a Spherical Gas Bubble
Experiments studying the compression and unstable growth of an argon bubble in a nitrogen environment, subjected to planar shock wave (1.32 ≤ M < 4) are performed in a vertical shock tube of square internal cross section. In parallel with laboratory experiments, a computational investigation is carried out with the multi-fluid compressible hydrodynamics code raptor, using adaptive mesh refineme...
متن کاملVelocity distribution in a viscous granular gas.
We investigate the velocity relaxation of a viscous one-dimensional granular gas in which neither energy nor momentum is conserved in a collision. Of interest is the distribution of velocities in the gas as it cools, and the time dependence of the relaxation behavior. A Boltzmann equation of instantaneous binary collisions leads to a two-peaked distribution, as do numerical simulations of grain...
متن کاملCombining Spherical-Cap and Taylor Bubble Fluid Dynamics with Plume Measurements to Characterize Basaltic Degassing
Basaltic activity is the most common class of volcanism on Earth, characterized by magmas of sufficiently low viscosities such that bubbles can move independently of the melt. Following exsolution, spherical bubbles can then expand and/or coalesce to generate larger bubbles of spherical-cap or Taylor bubble (slug) morphologies. Puffing and strombolian explosive activity are driven by the bursti...
