Fig. 5: Evolution of the two-dimensional mean velocity field (umean).
From: Aeroacoustics and psychoacoustics characterization of a boundary layer ingesting ducted fan
a, b boundary layer flow development along the S-plate in the absence of a ducted fan and (c), (d) boundary layer flow ingestion in the ducted fan under high- and low-thrust conditions, respectively. a–d Color bar represents the normalized mean velocity field (umean/U∞), where higher values (in red) indicate regions of higher mean velocity, and lower values (in blue) represent regions of reduced mean velocity.
