Identification Of Cord Sources In Glass Using Cfd

Cord appearance in the glass industry is a serious problem in high glass quality tableware production. The increased frequency of sharp cords provoked a serious analysis on cord origin and their elimination at the production line. Optical microscopy and electron microprobe analysis were applied as direct methods for cord identification. A computational flow dynamics calculation and process data analysis were used to verify the hypothesised source of the inhomogeniety.
