The Influence Of Glass Melt Flow Character On The Bubble Removal Process

The high utilisation of the melting space for the bubble removal process asks for the detailed examination of fining space geometry and glass flow character inside the space. The relative significance of the space utilisation for fining may be assessed from simplified models of bubble removal from fining spaces. This work demonstrates how the temperature distribution and the resulting glass flow patterns in the simple melting space (horizontal channel) affect the character of bubble removal from the melt due to variable utilisation of the space for processes. In performed calculations, the fining performance of the channel producing no bubble defects is the followed technological quantity.
