The effect of recuperator geometry on regenerated Brayton cycle

摘要

A computer simulation of the Brayton cycle is used to develop adesign procedure with respect to minimizing volume and weight for thecounterflow plate-fin recuperator. Based on the Orenda OT-4 600 horsepowergas turbine, recuperator performance and dimensional characteristicsare presented for an idealized equilateral plate-fin recuperatorcore matrix. The effects of plate spacings varying between 0.1 inchesand 0.5 inches on recuperator performance characteristics are presentedover a wide range of core frontal areas. Specific trends toward minimumvolume and minimum weight plate-fin recuperator cores are discussed indetail.
