Effect of orifice length-diameter ratio on fuel sprays for compression-ignition engines
A 1933 NASA technical report on how the length-to-diameter ratio of fuel injector orifices affects spray behaviour in compression-ignition engines, presented as technical papers for engineers and researchers. Its pictures are plain graphs of discharge coefficient against Reynolds number and length-diameter ratio, plus pressure-curve charts and a timed spray photograph, offering a designer little beyond the restrained scientific grid-and-line look of early engineering charts.
