Simulation Glass Spinning

Animation glass spinning in NOGRID points CFD software

Figure 1: Animation glass spinning process

The simulation of glass spinning can perfectly be performed with our CFD software NOGRID points. Centrifugal casting is one of the numerous methods of glass makers to produce glass pieces. The glass is poured into a graphite mold which is mounted on a centrifuge. Once the desired amount of glass is poured into the mold, the mold is set spinning. The centrifugal force causes the glass to rise up the sides of the mold and to take the shape of the mold wall on its exterior side, while having a smooth interior wall.

High precision of NOGRID's glass spinning simulation

Our meshless CFD software NOGRID points computes the real glass flow and the glass temperature distribution during the spinning step. 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 for the mold, thus saving time and effort in the design phase and increasing product quality.

Why choose Nogrid?

NOGRID provides professional CFD software for the simulation of fluid flow, heat and mass transfer, and chemical reactions. Its efficient modelling workflow helps engineers analyse flow behaviour, evaluate designs and make informed decisions without creating a conventional volume mesh.

Faster model preparation

With NOGRID, only the geometry boundary needs to be meshed. The finite points inside the fluid domain are generated automatically according to user-defined settings, both at the start of the simulation and during the calculation.

This approach reduces preprocessing effort and makes it easier to prepare complex geometries and cavities for simulation.

Efficient CFD workflow

The modelling process follows four straightforward steps:

Build the geometry. Mesh the boundary. Define the simulation. Start the calculation.

NOGRID is designed to provide short computation times, including for applications involving complex cavities. Engineers can use the resulting data to examine flow distribution and other relevant flow characteristics.

Better insight into fluid-flow processes

CFD solves the fundamental equations governing fluid flow. NOGRID software enables engineers to predict and analyse the behaviour of fluids and related physical processes before or alongside physical testing.

The simulation results can support:

evaluation and comparison of design alternatives
optimisation of construction and operating parameters
improved planning reliability
reduction of development time and testing effort
faster progression from design to market or operation
