Numerical Precision Of Minimum Residence Time Calculations For Glass Tanks - Recalculation Of Round Robin Test 1 Of Tc 21 "Modelling Of Glass Melts" Of The Icg

Prediction of glass quality is a main objective of glass furnace modelling. Minimum residence time (MRT) counts among the crucial parameters for representing glass quality. Numerical simulation is an efficient tool for estimating this parameter. For a Round Robin a simple case had been chosen with a parallepiped-shaped glass tank to test the performance of numerical codes and their application in glass melting simulation. It was shown that the numerical discretization fixed by the participants is sufficient to represent the temperature and velocity fields. However, significant differences in the calculation of the MRT between the different participants of the Round Robin were noticed.
