Generalized charts for determination of pressure drop of a high-speed compressible fluid in heat-exchanger passages 1: air heated in smooth passages of constant area with constant wall temperature
"In the present paper an analysis is made of the compressible-flow variations occurring in heat-exchanger passages. The results of the analysis describe the flow and heating characteristics for which specific flow passages can be treated as segments of generalized flow systems. The graphical representation of the flow variations in the generalized flow systems can then be utilized as working charts to determine directly the pressure changes occurring in any specific flow passage. On the basis of these results, working charts are constructed to handle the case of air heated at constant wall temperature under turbulent-flow conditions" (p. 1).

An Experimental Investigation of an Exhaust-Gas-to-Air Heat Exchanger for Use on Jet-Stack-Equipped Engines
Tests were made to determine the loss in exhaust-jet thrust and engine power resulting from the insertion of an exhaust-gas-to-air heat exchanger in a jet-type exhaust stack of an aircraft engine. The thermal performance of the heat exchanger was also determined.
