Acoustic resonance characterization and numerical model including acoustic streaming in an HPS lamp

This paper presents a numerical model of High Pressure Sodium (HPS) lamps including the acoustic streaming. The model is implemented in COMSOL and based on the finite elements method using a D2 axi-symmetric geometry. Moreover, a revision concerning AR experimental characterizations of HPS lamps will also be provided. The obtained results will be provided and discussed. The studies in this paper will contribute to the understanding of AR phenomena and electronic ballast design method for AR avoidance in lamp supply.
