Computational Fluid Dynamics (CFD) Analysis of Cleanrooms

Air is the primary carrier of particulates and contaminants from their sources to air return locations in the cleanrooms. Therefore, proper airflow distribution is crucial to ensure the desired level of cleanliness related to a class of the cleanroom. Depending on the level of cleanliness, the required airflow rates vary from a few to a few hundred air changes per hour (ACH). Ideally, the air supplied to the cleanroom should follow a “single-pass” flow path from the supply to return location without any significant recirculation and mixing.

Especially for large cleanrooms, maintaining high airflow rates with unidirectional airflow is energy-intensive and cost-prohibitive. The performance and energy efficiency of cleanrooms can depend on several factors such as the strength and locations of particle generation, desired cleanliness level, associated air change rates, and the location and number of supply and air return diffusers in the space.

Our proprietary CFD analysis procedures help our clients to optimize the performance of pharmaceutical, medical devices, biotech, semiconductor, and manufacturing cleanrooms. Our analyses verify compliance with ISO 14644 standards and predict temperature, humidity, pressure, and contaminant levels.
