Modeling & Verifying Aircraft Paint Hangar Airflow to Reduce Green House Gas and Energy Usage while Protecting Occupational Health Energy

Abstract : Aircraft paint contains toxic chemicals, such as iso-cyanates and hexavalent chromates, and ventilation and other protective measures are necessary to prevent exposure of workers that paint aircraft. Computational fluid dynamics \201CFD\202 modeling was used in conjunction with on-site tracer gas experiments to assess air flow conditions in the hangar and to investigate design alternatives. The project determined that a reduction in delivered airflow might not increase contaminant exposure. This report provides a summary of results from the site visits and discusses areas of potential future research.
