The transport of vorticity through fluids in turbulent motion : in the light of the Prandtl and Taylor theories
A 1936 NASA technical report on turbulent fluid motion, comparing Prandtl and Taylor vorticity-transport theories, written for aeronautical researchers. The three pictures are plain line graphs with fitted curves, data points and axis labels, with no ornament. A designer could take their clean scientific plotting style, dashed and solid curve conventions, and grid layouts as a restrained model for technical diagrams.
