| Abstract: | Single bubble sonoluminescence (SBSL) is a process of energy transformation from sound to light.It has a potential application in inertial fusion,sonochemical and short pulse ultraviolet light source,etc.We study the near spherical vibration dynamics of a gas bubble in an incompressible and viscous liquid by using a vibrator model.A detailed Mie scattering calculation with Dave downward recurrence about sonoluminescence was performed to determine the proper parameters of Mie scattering experiments and calibrations.And some experimental results about the attenuation of SBSL emission,the frequency and driving pressure dependences of SBSL intensity are obtained. |
