NOGRID points computes the real glass flow and temperature distribution throughout the entire flat glass forming area. It is also possible to perform the flat glass rolling process completely in 3D. Comparisons with various experimental data have confirmed the high precision of the simulation of this intricate flow process. Thanks to short computation times, our customers can integrate the simulation into their design process - helping to identify optimal designs more efficiently, reduce development effort in the design phase, and increase product quality.
Simulation Glass Rolling of Flat Glass
The simulation of glass rolling is a key technology in the development and optimization of flat glass production and can perfectly be performed with our CFD software NOGRID points. The simulation software offers detailed insights into the flat glass production process.
In the flat glass industry, glass sheets are typically produced by pouring molten glass between two rollers, which determine the final thickness of the sheet. As the glass comes into contact with the cold rollers, its viscosity decreases, resulting in a nearly stable flow behind the rollers. Due to the cold rollers the glass viscosity is decreasing and the glass behind the rollers is almost inherently stable. The animation in Figure 4 shows a glass rolling process based on a geometry published by G. Nölle in Technik der Glasherstellung, 1997. The color indicates the temperature. The inlet temperature increases over time; thus the glass sheet becomes increasingly unstable.
Simulation of glass rolling with NOGRID points
Our software can accurately predict such effects and supports designers to find the optimal speed for their flat glass rolling processes. In addition to simulating normal flow behaviour based on Newton's law of viscosity, NOGRID points is also capable of handling non-Newtonian materials, including viscoelastic behavior.
- 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
Nogrid's strengths
Particular strengths of NOGRID's fluid flow CFD software are the rapid preprocessing (no fluid grid needs to be generated, only the boundary mesh, inner finite points are generated automatically depending on User setting initially and during computation), and the outstandingly short computation time even for complicated cavities.
As you can see in the image below, the boundary of the geometry still requires a mesh to allow the interior finite points to detect the boundary. The boundary must therefore be meshed and the finite points inside are automatically generated during the simulation controlled by User specifications.
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 for flow modeling 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.
