Photomicrographic Studies of Fuel Sprays
A 1934 technical report of photomicrographs of fuel sprays, issued through NASA's technical reports server from a NACA-era research archive and aimed at engine and combustion engineers. The plates are grids of small black-and-white photographs with arrows marking the spray edges, ligaments and droplet trails, with captions in a technical hand. A designer could draw on the turbulent, feathery plume shapes and fine dark streaks as abstract textures or motion marks.
