Research to improve heat transfer in once-through boiler-dryer superheater tubes for space powerplant application may prove useful in the design of boilers for automotive steam powerplants. Data obtained in experiments with four tubes with different internal integral fins are compared with results for a plain tube. The performance of the finned tubes in these dryer-superheater experiments, in which a water-steam mixture at 35 psia was used as the coolant, indicates that a substantial reduction in once-through boiler length can be realized by their use.
