3D Acoustic Streaming Field in High-Intensity Discharge Lamps
发布日期2014
High-intensity discharge lamps will in the foreseeable future be important light sources despite a growing market share of LEDs. Cost and energy efficient high frequency (300 kHz) operation is hampered by the excitation of acoustic resonances inside the arc tube, which results in low frequency (10 Hz) light flicker. Our aim is to calculate the acoustic streaming velocity field, which is related to the sound waves, and link it to arc flicker. In contrast to a previous approach, the model is 3 dimensional.
