Physical modelling using glycerine and three-dimensional mathematical modelling were executed to study temperature and flow profiles of molten glass in the melter for the vitrification of high-level liquid waste. The apparatus for the physical modelling was fabricated and tested, which was the transparent model of one third scale of the plant scale melter. The numerical simulation was done for the physical modelling based on its experimental conditions. The profile of temperature and flow were discussed, and the good agreements were obtained between both models.
