The effect of recuperator geometry on regenerated Brayton cycle
… volume and weight for the counterflow plate-fin recuperator. Based on the Orenda OT-4 600 horsepower gas turbine, recuperator performance and dimensional characteristics are presented for an idealized equilateral plate-fin recuperator core matrix. The effects of plate spacings varying between 0.1 …
