Simulations
Mathematical simulations with CFD software
CFD computer modelling and analysis of glass melting furnace is one of the most efficient and precise approach to rate the influence of new designs before its implementation. Forglass is extending the boundaries of standard engineering by introducing the mathematical modelling as inseparable part of designing innovative new concepts as well as optimization of existing furnaces.
General information
Utilization of computer modelling in engineering process is a way for overcoming design challenges and creating the most sufficient ideas in glass industry. The main advantages of modelling study involved in engineering methodology are:
- Sustainable energy usage of the furnace,
- Obtained necessary glass quality,
- Seeds, blisters and bubble tracing and reduction,
- Improved combustion space efficiency,
- Optimized operating conditions of the furnace,
- Minimized risk of failure of the non-verified newly implemented design solutions,
- Maximized and detailed understanding of the glass melting processes.
Forglass’ offer
Modelling study includes the extensive and detailed report or presentation with simulation results. All the crucial bullet points are answered with the high resolution visualizations and animations as well as necessary additional calculations (e.g. seeds and bubble counts). Report or presentation is prepared in way that customer has clear and comprehensive understanding of the simulated topics and solutions. All results and conclusions are presented and discussed with Forglass R&D team during online meeting(s). Forglass recommendations based on best-practice are also included.
In principal, glass technology and all the phenomena connected together cannot always be analysed in the same way. To meet all the expectations each report is adjusted to certain topic and Customer needs. The following aspects among others are possible to be discussed in the report:
- Combustion space and melt tank 3D visualizations with temperatures and velocity fields,
- Temperature distribution in glass at cross-sections ta any desired cross section,
- Glass composition discussion,
- Batch blanket distribution together with glass coverage,
- Glass currents detailed analysis, including stream lines, animations etc.,
- Electrode boosting arrangement and bubbling performance,
- Flame propagation and fumes circulation,
- Glass quality indexes like sand dissolution, bubble trace, residence time, minimum maximum temperatures.
- Wall loses with the cooling performance rating.
