Experiments on the Recovery of Waste Heat in Cooling Ducts, Special Report
This NACA-style technical report from 1939, issued by the National Advisory Committee for Aeronautics and held in the NASA Technical Reports Server, presents experiments on recovering waste heat in cooling ducts, written for aeronautical engineers. Its pictures are plain engineering plots and a photograph: a pressure curve across a duct, a set of stacked distribution graphs, and a full-scale tunnel cooling wing, offering a designer clean line charts and a stark industrial photo of a hangar interior.
