CFD also simulates experiments that cannot be conducted with real media for cost or security reasons. The reasons for this can be toxic, explosive or carcinogenic product behavior.

CFD simulations are used for

  • Concept studies of new designs
  • Product developments
  • Validation of agitator designs and
  • Benchmarking agitators
  • As a supplement to tests under real conditions in
  • the technical center

On the basis of CFD simulations, we can make statements about the fluidic conditions in the tank and assess how and whether a stirrer will perform the stirring tasks. Another advantage is that the simulation is shown on a real scale and not on a model scale.

The combination of CFD examinations with conventional empirical tests and analytical calculations ensures maximum safety in the process engineering agitator design. In short: double is better.

In addition, an instrumented agitation test rig with a coaxial stirring system provides optimal test conditions for tests with two parallel or counter-rotating stirring systems. The measurement data from the real tests are continuously registered as the basis for later scale-up to the original size.
