Abstract
A method of applying ultrasonic acoustic energy to a glass melt by monitoring a glass melt temperature Tand transferring ultrasonic acoustic energy from an ultrasonic transducer to the glass melt at a controller power Pand a controller frequency vthrough an ultrasonic probe positioned in the glass melt is provided. According to the method, the controller power Pis controlled in response to at least (i) the monitored glass melt temperature Tand (ii) a reference glass melt temperature T. The controller frequency vis controlled in response to at least (i) one or more input parameters from a temperature-viscosity curve characterizing the glass melt, (ii) one or more input parameters from one or more temperature dependent impedance response models of the glass melt, and (iii) ΔZ, where ΔZ represents a degree to which an impedance condition Zof the ultrasonic probe differs from a reference impedance Zwhen the ultrasonic probe is positioned in the glass melt. Systems for applying ultrasonic acoustic energy to glass melts are also contemplated.
