The images depict the velocity field in a 2D cross-section of the channel. Within the channel, the positions of the blades are marked by two thick black lines. The black dashed line indicates the center of the blade. At this point, the value of the y-component of velocity is indicated by a white line, which is normalized by the inlet velocity (constant at 25 m/s). The white line is not to scale but normalized. Its maximum size indicates the peak value (in percentage). The individual parameters of the task are described in the image title.
