Sonochemical effects on single-bubble sonoluminescence.
A refined hydrochemical model for single-bubble sonoluminescence (SBSL) is presented. The processes of water vapor evaporation and condensation, mass diffusion, and chemical reactions are taken into account. Numerical simulations of Xe-, Ar- and He-filled bubbles are carried out. The results show that the trapped water vapor in conjunction with its endothermic chemical reactions significantly r...
متن کاملEffects of ionization in single-bubble sonoluminescence.
We studied the effects of ionization in a sonoluminescing (SL) bubble within the hydrodynamic framework. The thermodynamic variables and the degrees of ionization inside the bubble throughout an oscillation cycle are obtained by solving the hydrodynamic equations assuming spherical symmetry. Several models are used to compute the emitted radiation, which are then compared with experimental data...
متن کاملSingle-bubble sonoluminescence
Single-bubble sonoluminescence occurs when an acoustically trapped and periodically driven gas bubble collapses so strongly that the energy focusing at collapse leads to light emission. Detailed experiments have demonstrated the unique properties of this system: the spectrum of the emitted light tends to peak in the ultraviolet and depends strongly on the type of gas dissolved in the liquid; sm...
متن کاملThe effects of organic compound doping in single-bubble sonoluminescence
Single-bubble sonoluminescence (SBSL) in water has been studied in the presence of low concentrations of simple organic compounds. For a given concentration of aliphatic alcohol, the degree of quenching follows the order, ethanol< I -propanol< 1-butanol, Preliminary experiments with simple we& acids and bases indicate that SBSL quenching only occurs when the pH is adjusted such that the solutes...
متن کاملSingle-bubble sonoluminescence in air-saturated water.
Single bubble sonoluminescence (SBSL) is realized in air-saturated water at ambient pressure and room temperature. The behavior is similar to SBSL in degassed water, but with a higher spatial variability of the bubble position. A detailed view on the dynamics of the bubbles shows agreement between calculated shape stability borders but differs slightly in the equilibrium radii predicted by a ma...
