  • explain theoretical background and limitations of the discrete models for the processes with solids
Capabilities

After successful completion of the module the students are able to, 

  • perform flowsheet simulation of solids processes and analyze steady-state or dynamic process behavior
  • simulate behavior of granular materials on the micro scale with Discrete Element Method (DEM)
  • optimize processes of mechanical process engineering (mixing, separation, crushing, …) with DEM
  • apply multiscale simulations for modeling of particulate materials
  • evaluate results of numerical simulations
  • select and apply appropriate thermodynamic and kinetic models for processes with solids
  • select and apply appropriate discrete models for the processes with solids.

Personal Competence

Social Competence

After completion of this module, participants will be able to debate technical questions in small teams to enhance the ability to take position to their own opinions and increase their capacity for teamwork.

Autonomy

After completion of this module, participants will be able to solve a technical problem independently including a presentation of the results. They are able to work out the knowledge that is necessary to solve the problem by themselves on the basis of the existing knowledge from the lecture.
