Various research and industrial processes require precise knowledge of flowing characteristics of employed materials. Besides viscosity as the most commonly known rheological parameter, time dependancies such as thixotropy or rheopexy or yield stress and shear stress dependancies such as shear thinning or dilatancy can be crucial when it comes to plant engineering or product development or optimization.

The institute of mechanical process engineering of RWTH Aachen University researches and developes in the field of rheology for over 40 years. Its expertise and laboratories are available through the following services:

  • Analysis and characterization of complex rheological fluids.
    - Rotation viscometer (-50°C < T < 1600 °C)
    - Capillary viscometer
    - Liquid jet rheometer (interfacial phenomena)
  • Development of special rheological measuring techniques
  • Interpretation of rheological properties
  • Simulation of processes involving liquids
