NOGRID points computes the real glass flow and temperature distribution in the complete forming area. It is also possible to perform the rolling process completely in 3D. Comparisons with various experimental data have shown the high precision of the simulation of this intricate flow process. The short computation time allows our customers incorporating the simulation into the design process to find an optimal design, thus saving time and effort in the design phase and increasing product quality.
Simulation Glass Rolling
The simulation of glass rolling can perfectly be performed with our CFD software NOGRID points. Flat glass sheets are often produced by pouring the glass between two rollers, which are responsible to give the sheet the final thickness. Due to the cold rollers the glass viscosity is decreasing and the glass behind the rollers is almost inherently stable. The movie in figure 1 shows a glass rolling process (the geometry was published by G. Nölle: Technik der Glasherstellung, 1997). The color represents the temperature. The inlet temperature is increasing with time; thus it appears that the glass sheet becomes more instable after a while.
Our software is able to predict such effects and helps designers to find the right speed for their processes. Beside the normal flow with Newton's viscous law NOGRID points is also able to run the computation with non-Newtonian materials (also viscoelastic material behavior is included).
- computation is in full 3D solving complete Navier-Stokes-Equations
- easy and intuitive setup of the FSI (Fluid-Structure-Interaction) case
- free definable material properties by equations or curves,
- moving parts with a lot of moving features
- open or closed domains including moving of additional parts
- computation of temperature transport in the solid rollers and in the fluid
Easy and fast modelling: Build geometry, mesh boundary, setup the case and start computation
What is CFD from NOGRID?
CFD solves the fundamental equations that define the fluid flow process. With CFD software from NOGRID every engineer makes better decisions by predicting, analyzing and controlling fluid flow, heat and mass transfer or chemical reaction. By using NOGRID software you receive information on essential flow characteristics as for example flow distribution. Using it additional to testing and experimentation NOGRID software helps to improve the evaluation of your design – resulting in better construction and operation parameters, increasing planning security and money savings due to faster time to the marketplace for your product or process.
