GFM: Glass Furnace Modeling
When making glass, exact control of energy, mass and momentum is critical. If the glass has measurable defects or non-uniformities, it cannot be used, wasting large amounts of energy and productivity. These problems exist for any company producing glass products. However, Argonne’s Glass Furnace Model (GFM) simulation code can help ensure that furnaces produce the highest quality glass possible.
GMF allows glass manufacturers to create virtual furnaces on a computer to improve process design. It is a powerful cost-effective tool that can be used to analyze and optimize existing furnaces or investigate new furnace designs.
GFM consists of three major computational models:
- Combustion space model
- Radiation heat transfer model
- A multiphase glass melt model
The GFM code was extensively validated using data from in three different types of operating furnaces. Data was acquired by the Institute for Clean Energy Technology, which provided spatial distribution data on the gas temperature, gas velocity, gas species concentration, wall temperatures, and directional radiation heat fluxes in the combustion space and glass melt surface temperatures and velocities.
- Glass fabrication
- Furnace design
- Simple user interface
- Automated cycling capability to reduce run times
- Progress monitoring program
- Numerous other enhancements to increase fidelity and convergence in melt and combustion computations
- Runs on Windows 2000 and later computers
- Requires a 2 GHz Pentium IV or better with at least 512 MB RAM
- Faster machines or more RAM will decrease the run time and allow use of more refined grids
