Fluid Dynamics

The intelligent way to optimally use nozzles

When considering flows, turbulence and highly complex spray processes, nobody knows the possibilities better than we do. Just as no one knows your requirements better than you. Together we can find out how to use all your potential.


We do not promise perfection - we expect it.

For well over a century, we have been developing and producing nozzles and nozzle systems for many different applications. This resulted in a unique understanding of spray and atomization processes in a variety of applications over a wide range of pressures, temperatures and atmospheres. We are constantly working to improve the precision and efficiency and open up new application areas.

For simple calculations such as a straight piece of pipe, the flow state is still relatively easy to calculate using paper, pencil and calculator. If there is just a slight curve, then this is not so easy. Here, Computational Fluid Dynamics (CFD) is required.


We have used our expertise from many decades of nozzle development for these simulations. Conversely, CFD was initially just an internal tool that aided us in developing a desired nozzle faster and more accurately. Our high-performance clusters with a computing power of around 8,500 GFlops allows us to offer our knowledge as a service today. We simulate nozzle applications and processes individually for your environment and your requirements. This ensures that everything runs optimally in the real world.

Fluid Dynamics in action - customer-specific process optimization


Even with spray processes that have been running smoothly for years there is usually a considerable potential for optimization. Using our process simulations we can find these without interfering with the ongoing production. In this way, different settings can be tested, checking their impact on total yield. Here we rely on a clearly defined workflow:

  • Project definition
  • Inventory analysis using CFD to define the initial situation and identify the potential for optimization
  • Optimization using CFD for virtual review and evaluation of individual measures
  • Implementation

Your benefits

  • Identification of optimization potentials
  • Virtual evaluation of individual measures
