CFD laboratory

Laboratory for computational fluid mechanics


In the CFD laboratory, students learn about the simulation process and apply it to computational fluid dynamics (CFD). Using tutorials, they work their way from geometry preparation and meshing to pre-processing, where they can define the boundary conditions of the simulation. In post-processing, the results are then analysed in terms of fluid mechanics and insights are gained. The validation of the results with regard to an error analysis is also dealt with. The course is offered together with the theoretical lecture in the Bachelor's degree course as an elective module "CFD Fundamentals" and in the Master's degree course in Process Engineering with the "Fluid Dynamics and CFD” specialisation.

In summary, the following contents are covered:

  • Theoretical fundamentals of computational fluid dynamics
  • Application in project work
  • Structured and unstructured meshing with ANSYS-Meshing and ICEM CFD
  • Calculation with ANSYS-CFX
  • Carrying out parameter studies in the ANSYS workbench

Focus points of work

In addition to laboratory courses, interdisciplinary student projects and Bachelor's and Master's theses are also carried out in the CFD laboratory in cooperation with industry.

In addition to ANSYS-CFX, we use other CFD solvers such as ANSYS FLUENT.
