Study on mechanisms of glass flow and heat-transfer process in float glass furnaces using computer three-dimensional simulation and graphics generation
Based on the understanding of mechanisms of glass flow and heat transfer process in float glass furnaces, three-dimensional models have been established which show that the glass flow and heat transfer, and the physical parameters of the glass fluid have been formulated. The boundary conditions have also been determined in the light of the practical situation. The method SIMPLER has been applied to calculate both temperature and velocity fields in float glass furnaces. Using the technique of Computer Graphics, three-dimensional glass temperature graphics, two-dimensional glass velocity and temperature graphics can be directly generated. The glass flow situation, the initiation of flow back, the formation of dead space, the position of hot spot and foam line, the distribution of three dimensional temperature fields, the temperature contour of different planes and the thermal point position etc. can all be directly simulated by graphics.It is shown from above work that the variations of geometric structure, chamber temperature distribution and output of float glass furnace have strong effects on both the velocity and temperature fields, and all of our results are very useful in determination of thermal parameters, for the improvements of furnace structure designing and for the selecting of refractory of the furnace.
