Simulation glass feeding 

Simulation of glass feeding processes can perfectly be performed with our CFD software NOGRID points

The problem below was created by the ICG-TC25 members (International Commission on glass, Technical Committee 25), who are engaged in R&D activities in the field of numerical simulation of glass forming processes. For more details see ICG-TC25 Bench Mark Problem II: "Gob Forming Benchmark".


Glass gob quality essential

Glass making processes from glass containers to tableware to TV glass begin with a liquid glass droplet (gob) being delivered to the forming machines where it will be molded into the finished glass product. In a great measure the success of the entire operation depends on the uniform quality of the glass gob.


Valuable information by simulation of glass feeding 

Simulation of glass feeding with NOGRID points delivers valuable information that helps to assess the feeding process. For the purpose of this benchmark the glass gob delivery system for a large champagne glass bottle will be modeled. This process was selected because it is far enough removed from current practices to avoid concerns about proprietary information. However, it is close enough to current champagne glass bottle gob weights and shapes to closely many glass gob forming processes. 

Figure1 shows the velocity profile and the temperature profile in the simulation of a glass feeding process computed with NOGRID points.
