fluid flow.

Flows of gases, liquids and mixtures of gases, liquids and even particles are often an important and challenging aspect of designing products, machines and installations. This covers a wide range of applications, from the flow around a building or a turbine blade, and the flow in a microscopically small channel or a large pump, to the turbulent ventilation flow through a room, and the design of an efficient cooling system. We have the in-depth knowledge and broad experience to support customers in their design process by simulating fluid flows and providing advice on all fluid-flow matters.

Flow-related topics that we address

  • Aerodynamics and hydrodynamics

  • ATEX hazardous zone classification
  • Cooling systems
  • Flow-induced vibrations
  • Fluid-structure interactions
  • Wind-comfort studies according to NEN 8100
  • Fire-safety engineering according to, e.g., NEN 6098


virtual prototyping.

Besides following an analytical approach, we simulate fluid-flow phenomena with the use of computational fluid dynamics (CFD) analyses and lumped-element modelling. Employing these analyses, we can make a virtual prototype of the customer’s design and simulate the fluid-flow behavior in or around it. In a 3D model we can visualize, for example, the pressure, temperature and velocity fields at any location, including those locations where the experimental measurement of temperature or pressure is challenging. Such visualizations serve to aid the understanding of a product’s performance. Digitally, we can quickly make changes in the model and instantaneously evaluate their effect on the performance of the physical model, which can save precious development time. Simulations are extremely useful to find any flaws or discrepancies in an early design stage, preventing costly design modifications in later stages.
