Heat Transfer from Finned Metal Cylinders in an Air Stream
A 1935 NASA technical report on heat transfer from finned metal cylinders in an air stream, issued for engineers and aeronautical researchers studying engine cooling. Its pictures are plain photographs and line graphs: ribbed and coiled cylinder samples, a temperature-distance chart with curved decay lines, and a labelled test section beside a guard ring, offering a designer ready material on fins, ribs and technical measurement diagrams.
