Physical Modeling

Physical modeling is used in combination with mathematical modeling, especially in the field of glass homogenization, stirring and forming. This type of modeling provides an understanding of the physical phenomenon of the glass processes.

Physical modeling is the study of natural process.
It is governed by natural science law.
It is a reality that can be monitored.

        

Glass Homogenization & Glass Delivery

  • Visualisation of flow patterns in mixing area
  • Optimization of the stirrers
  • Determination of the critical streamline
  • Head losses created by stirrers
  • Interaction between stirrers, or tube and plunge, during gob formation
  • Dead area in the spout

                                           
SHORT PASS FLOW                                                                      DEAD AREA IN SPOUT

 

                                         
                                                 INTERACTION OF GOBBER AND STIRRER


Models of Forming Processes

  • Visualization of flow patterns in the mold
  • Definition of the shape and dimensions of the forming tools
  • Verification of forming conditions (i.e. viscosities in defined points)
