Modelling and Simulations
Multiphase flow simulations

Digital models and simulations offer several advantages for the design and operation of wastewater treatment plants. However, transferring the complex nature of the processes occurring inside the plants to a detailed digital model is a challenging task. This is also true for the intricate relationships between the plant’s operation and the environmental impacts that come with it. Scientists at CLEWATEC make use of a variety of software tools to develop and apply a number of reliable models for:

  • Computational Fluid Dynamics (CFD)
  • Direct Numerical Simulations (DNS)
  • Biological and chemical processes
  • Life Cycle Assessment (LCA)

With the support of the Computational Fluid Dynamics Department and the HPC resources available at HZDR, we are capable of meeting the most challenging problems regarding process modelling and simulation.
