Simulation and modeling of GRM in a CAE-enviroment

Reference number
Coordinator ÅF-INDUSTRY AB - ÅF-INDUSTRY AB - Göteborg
Funding from Vinnova SEK 300 000
Project duration November 2017 - February 2018
Status Completed
Venture Strategic innovation program SIO Grafen

Purpose and goal

The project has conducted an introductory study of the transfer between the micro scale to the CAE platform for interconnection with simulation models developed within academic research. CFD / DEM (Computational Fluid Dynamics / Discrete Element Modeling) and NEMD (Non Equilibrium Molecular Dynamics) Methodists have been used in the project. The results show that intermediate steps in both size and time resolution between the atomic and CAE platforms must be developed as linking those levels.

Expected effects and result

The result shows that more research and development will be needed in the coming years to achieve computational development of materials. This becomes apparent as difficulties arise in effectively taking into account GRM´s influence on surrounding fluid. For example, factors like the flexibility and flexibility of GRM are difficult to take time and resource-efficiently into account in a CAE environment. Modeling techniques that take into account non-spherical particles exist and a similar approach can be used for the flat cylinder particles used herein.

Planned approach and implementation

The design and implementation of the project has been carried out with a strong link between the different parties (Chalmers and ÅF). ÅF has been responsible for the analysis of the CAE methodology, which in this case is a CFD / DEM methodology. Chalmers is responsible for the atomic simulations (NEMD). The project was carried out by the respective parties with weekly meetings in place at the parties to undergo the various results that were generated within the project where discussions were also taken to circumvent the obstructions observed.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
