Pulsations, pressure oscillations, cavitations, vortex shedding, standing waves ... instationary flows in the vicinity of turbo-engines (pumps, compressors etc.) or fittings, for example, are rarely desired and often lead to problems with pipe vibrations, increased wear on pumps or fittings, volume measuring errors or singular sounds (noise).

Our goal in the department "Fluid mechanics" is to work out practical solutions for the elimination of such effects.

The way is defined by the task at hand. It usually follows this structure

• assessment of the problem
• physical determination of the cause
• design and implementation of corrective measures.

As a resource the department has the whole spectrum of technology for flow measurements (pressure sensors, probes, vane wheel and heating wire anemometers, ultrasonic sensors etc.) as well as flow simulations (one- and multi-dimensional models) at its disposal.

Crucial to a goal-oriented solution is our expert knowledge as well as many years of experience in dealing with such problems, for example in the gas industry, chemical industry or medical technology.
