Using a hydrochemical simulation, temperature dependency of single-bubble sonoluminescence (SL) in a concentrated solution of sulfuric acid has theoretically been studied. With calculating the phase diagrams of an SL bubble in the solution of 85% acid, maximum acquirable SL emissions at different ambient temperatures were calculated. The results show that the SL emission in sulfuric acid increases with increment in the ambient temperature. This temperature dependency is in opposition to that observed in experiments for SL in water. The difference originates from different instability mechanisms determining the ultimate phase parameters of SL in water and sulfuric acid. In water, due to the smallness of viscosity, the ultimate phase parameters are determined by the shape instability. However, in sulfuric acid the phase parameters are restricted by positional instability due to the largeness of the liquid viscosity. |
