Designing a clean room is easier thanks to the rise of automatic CFD software

The control of dust and other pollutants is getting more critical as clean rooms are essential for more branches of modern research and precision manufacturing. Many industries, i.e., pharmaceutical, need to comply with regulations and mandatory requirements. Designing a clean room is easier thanks to the rise of automatic CFD software.

Computational Fluid Dynamics (CFD) simulations help architects and engineers design spaces adequate for research operations. Even at the earliest stage of the design process, they can run tests of their models to see how the ventilation system in clean rooms affects their performance and adjust purging procedures.

CFD simulations make it possible to control the level of contamination in a clean room measured in a number of particles per cubic metre, while air in an urban environment contains tens of millions of 0.5 µm or larger in diameter particles per cubic metre. An ISO 1 room only allows 12 particles per cubic metre in diameter that are 0.3 μm or smaller.

Velocity plot comparison and laminar and turbulent airflow principles are other processes that are required in cleanrooms, and can be handled using automated CFD simulation software. There are research and manufacturing processes that need to perform under particular pressure. Sometimes it has to be very high, sometimes very low, but in both cases, it has to be controlled. Maintaining high or low pressure is much easier if the room is designed with the use of CFD simulations.

CFD simulations can also help improve the safety of people working in clean rooms, as well as energy efficiency.
