Round robin for glass tank models : Report of the International Commission on Glass (ICG) Technical Committee 21 "Modelling of Glass Melts"

Abstract

Different numerical and physical models for glass tanks were compared by a simple round robin. Most models produced qualitatively similar velocity and temperature distributions. The minimum residence time of tracers in numerical models gave similar values too, but differed to the physical scale model. An explanation for this is the different kind of batch modelling in both methods of Simulation. Especially the velocity vectors at some fixed test points showed larger deviations. In regions with steep gradients small variations in the local flow distribution can lead to large changes at fixed test points. These differences therefore should not be rated very high.
