The bubble arrays present in the glass melting spaces mayextract gases from the melt and thus decrease its refining ability, as well asinfluence glass flow by changing density of the mixture glass melt-bubbles. Bothphenomena were examined using the 3D and 2D models. The examination of thebubble extraction ability on elected glass pathways in the 3D model has shownthat refining gases were evidently removed from the reduced glass melt (amber)while the concentration drop of dissolved refining gases in an oxidized glasswas negligible. The distinct bubble stirring effect in the 2D melting space wasobserved when inputting about 3 vol.% of small bubbles (a = 2.5x10-4 m)through a part of bottom. The effect of bubble concentration gradients on theintensity of glass convection was analogical to the impact of temperaturegradients on glass flow in case of temperature convection. Different behaviorwas observed, however, when examining the impact of geometrical shape on themelt flow. Both described phenomena should be considered in advancedmathematical models of glass melting spaces.
