The Effect of Baffles on the Temperature Distribution and Heat-transfer Coefficients of Finned Cylinders
This is a 1936 NASA technical report on how baffles affect temperature and heat-transfer in finned aircraft engine cylinders, written for aeronautical engineers and researchers. Its pictures are plain engineering graphics: polar plots of heat-transfer and temperature distribution around a cylinder, line graphs of temperature against distance, and a labelled wind-tunnel test-section drawing, all in black ink on cream paper, useful to a designer for their clean schematic chart style and dense labelled data layouts.
