The performance of parallel-flow-type tail-pipe heat exchangers is analytically investigated. An equation is developed relating the output of unfinned heat exchangers to the inlet- and outlet-air temperatures, engine-temperature ratio, corrected engine gas flow per unit of tail-pipe area, and heat-exchanger dimensions.
