Poster: Distribuce bublin v tavicích kanálech se skelnou taveninou

Original language description

Equations were derived describing bubble distribution in horizontal and vertical channels with glass melt. The melt plug flow was considered in mentioned derivations. Using data typical for glass melting and fining, the bubble number and volume densitieswere calculated in a horizontal and vertical channels with downward plug flow. The bubble concentration profiles in the horizontal channel showed an almost permanent decrease of bubbles with time, while the vertical channel exhibited the bubble accumulation in the area where bubbles in downward flowing melt started to rise because of their growth. Coalescence should play a significant role in the accumulation area and convection currents should develop.
