摘要: This paper presents a theoretical framework of imaging the solidification molten metal inside pipe by eddy currents. A complete mathematical model is developed which reveals relationship between and scattered field measurable outside pipe. then exploited to develop numerical algorithm able quickly reconstruct geometry based on measured intensity. not only appears be first its kinds from metallurgical point view, but also involves some novel development view electromagnetic computations, includes in particular Green functions multiple layered media.
