摘要

This paper presents a numerical model of high-pressure sodium (HPS) lamps, including acoustic streaming. The model is implemented in COMSOL and is based on the finite-element method using a 2-D axisymmetric geometry. Moreover, a revision concerning experimental acoustic resonance (AR) characterizations of HPS lamps will be also provided. The results presented in this paper will contribute to the understanding of AR phenomena and will help in the electronic ballast design methods for AR avoidance.
