Valves are in many applications and with a lot of different types and shapes but their typical problems can be summarized in few categories:

- predicting the characteristic curve during the design stage

- minimize turbulence

- find a stable behaviour in a wide working range

These tasks can be reached by targeted analysis with CFD techniques combined with lumped parameters models

Heat exchangers, are not only the mature and standardized product easy to be sized with quick software tools. They are also the key components in many energy, automotive or other advanced applications.

Typical requirements are high efficiency, very compact size, very high power density, extreme temperatures.

We propose CFD combined with targeted laboratory tests to reach these objectives, a primary tool where we feel very skilled.

Heating and ventilation in buildings must reach energy and comfort performance that require more advanced tools than simple calculation algorithms or spreadsheets.

Nowadays thermal and ventilation behaviour inside the building must be predicted accurately in the design phase, in order to maximize energy saving and respect comfort index.

CFD is a wonderful tool to verify and to explore new solutions, and we are proud to make available our many years of experience.

More than ordinary buildings, clean rooms must be compliant to severe criteria in order to prevent contamination. Here details matter and vortexes and recirculations zones are to be avoided as much as possible.

A preliminary study by CFD helps in reaching faster a solution and to avoid unpleasant surprises during testing and commissioning.
