dcterms:description
The fining process may be enhanced by acting of additive force on bubbles in the glass melt. This study deals with behaviour of single bubbles under effect of centrifugal force in a rotating discontinuous cylinder with glass melt. The model of a single bubble in the combined gravitational and centrifugal field has been set up and calculations of bubble behaviour in the cylinder have been performed for the model TV glass. Two mechanisms of bubble separation were indicated from results of calculations, i.e. the complete dissolution and separation by centrifugal force. The first mechanism is restricted to areas close to cylinder mantel and exhibits relatively long bubble dissolution times. The analysis of model and results revealed the potentially positive role of increasing cylinder radius and partial filling of rotating cylinder with glass melt. The bubble separation is considerably influenced by bubble dissolution or growth during centrifuging, thus the crucial role in this process plays temperature a The fining process may be enhanced by acting of additive force on bubbles in the glass melt.

Tato studie se zabývá chováním jednotlivé bubliny v odstředivém poli rotujícího válce naplněného sklovinou za diskontinuálních podmínek.
