Microstructure and mixing
What simulation brings:
- Microstructure characterization : (inclusions size, distribution)
=> influence on material constitutive law
- analyis of influence of materials used for disperse and continuous phases. Parameters: viscosities (ratio), densities, temperature, surface tension …
- analyse of influence of process parameters (screw rotation speed, flow rate, …)
- test and validation of various models of microstructure evolution
How to account for microstructure and flow interaction:
Modelling of microstructure evolution in the flow: Multi-scale approach
Example
Simulation of mixing in the extruder screw
