Simulated particle concentration in the working area without artificial particle generation
Air change rate/(h−1) | Number of air supply outlets | Relative concentration in the mainstream area (the concentration at one air supply outlet is assumed 1) | Relative concentration in the surrounding area (the concentration at one air supply outlet is assumed 1) |
