Contribution to the theory of the heated duct radiator
This 1939 NASA technical report, issued as a document in the NASA Technical Reports Server collection, is an engineering study of heat exchange in a duct radiator for aircraft engineers and researchers. Its single figure is a schematic flow diagram showing streamlines curving through a constricted duct with a heated core, with velocity profiles and pressure labels (v, p, q) plotted at the inlet, section, and outlet. A designer could borrow its clean streamline-and-profile language for abstract flow or motion graphics.
