    Abstract

    It is a challenge to measure the bubble behaviors in molten metal liquid, which is normally nontransparent and hyperthermal. This paper developed a novel contactless and simple method for modeling the single bubble characteristics in bubble-melt flow. Based on the applied external electric field, the receiving signal was calculated using boundary element method to indicate the relationships between several bubble parameters and electrical field change. The effects of bubble position, shape and size were investigated and in comparison to the theoretical results, the numerical approach was validated. The simulation results show that a single bubble has a significant impact on the electric field distribution and experimental platform will be setup in future to work cooperatively.
