Often, undesirable flow patterns are only recognized during flow visualization on the finished clean air system.
This can include turbulence, reversal of direction, stagnant air and similar undesirable effects that can lead to contamination of the product.
Subsequently optimizing an already installed clean air system often involves a lot of time and money and, in the worst case, with production downtime.
In some cases, subsequent optimization is no longer possible. It is therefore advisable to have a flow simulation carried out on the computer during the design phase for complex clean air systems where the flow patterns cannot be easily predicted. This makes it possible to avoid serious errors before the system is built, thereby saving the customer a lot of costs and hassle.
Optimization using CFD can also be carried out in advance for existing systems and it can be checked whether the optimization measure leads to the desired result before the conversion takes place.

Mr. Kuhn shows various practical examples of CFD simulation and its added value in cleanroom technology. Among other things, energy efficiency can be positively influenced by high-quality simulation.
