BARRIER TECHNOLOGY
Cleanroom Flow Modeling
Objective
Predict air flow patterns inside cleanroom Study particle dispersion characteristics Provide design solution for different applications
Results
Velocity magnitude and direction around work area and other flow obstructions Particle concentration profiles inside cleanroom Flow streamlines Stagnation regions
Benefits
Provide a flow visualization tool for better cleanroom designs Shorter design cycles and less costly approach than building mock-ups or other forms of physical testing Ensure operator and/or product safety Ensure capture of airborne products
Design Parameters
Particle - Generation points - Generation rate - Size Inlet Supply Air - Location - Number of inlets - Velocity and distribution	Return Air - Location - Number of exits
Performance Evaluations
Air change rates at different zones of cleanroom Undesirable stagnant regions and recirculation zones Particle concentration profiles
