Heat Transfer to Fuel Sprays Injected into Heated Gases
This 1938 NASA technical report, compiled from the NACA aeronautical research series, presents experimental findings on heat transfer when fuel sprays are injected into heated gas streams, written for engine researchers and combustion engineers. The pictures are plotted oscillograph traces: white curves of pressure drop against time in seconds, with labelled points A, B and C, stacked above and below gas temperatures printed on the right edge, all set against dark photographic backgrounds. A designer could take from them the crisp, rhythmic layering of parallel traces and the graph-paper rhythm of annotated measurement lines.
