, the total number of particles initially released into the air-flow, the residence time of one particle in the duct, the cross-section area and volume of the duct. Obviously, τ+ increases with dp. Figure 3... as shown subsequently in Section 3.1. Consequently, this study implements some corrections by adopting curve-fitted values of fluctuating velocity in the wall-normal direction. For the smooth duct......
