Název v původním jazyce

Sand dissolution and bubble removal in a model glass-melting channel with melt circulation

Popis výsledku v původním jazyce

The quantity space utilisation for a glass-melting space was introduced with the intention of evaluating the impact of glass-flow character on the processes of sand dissolution and bubble removal in a continual melting space. Different glass-flow patterns in the model horizontal melting channel were produced by linear temperature gradients applied on the glass level. In addition, the maximum sand-dissolution or bubble-removal performances of the space were calculated by mathematical modelling. The combination of a transverse and small positive longitudinal temperature gradients, which resulted in spiral melt and bubble trajectories, showed the best values of the space utilisation for both processes, even higher than had been attained under conditions of uniform melt flow. The values of space utilisation, linearly proportional to the melting performance, showed typical maxima when plotted as a function of the ratio of the transverse and longitudinal temperature gradients. The positions
