About

Thomas H. Kuehn is a leading authority in cleanroom technology and aerosol science, with a career focused on understanding and controlling particle contamination in controlled environments. His pioneering work combines experimental fluid dynamics with computational modeling to improve the design and performance of cleanrooms critical to semiconductor manufacturing and pharmaceutical industries. In his highly cited 1993 study (23 citations), Kuehn experimentally characterized airflow and particle distribution around a robot arm in a vertical unidirectional flow cleanroom, using hot wire anemometry to reveal how moving equipment disrupts otherwise laminar flow and redistributes contaminants. Earlier, his 1988 simulation paper (19 citations) demonstrated that numerical codes could accurately predict steady isothermal airflow in both vertical laminar flow and tunnel cleanrooms, establishing a foundation for modern cleanroom design. Kuehn’s contributions have been instrumental in bridging the gap between theoretical fluid dynamics and practical contamination control, providing engineers with validated tools to minimize particle deposition on sensitive surfaces. His work remains essential reading for researchers and practitioners seeking to optimize cleanroom performance through a deeper understanding of airflow and particle transport.
