Further Experimental Study of H2O-LH2 Heat Exchangers
At the Nuclear Rocket Development Station (NRDS) in Nevada, heat exchangers are under construction that will convert large quantities of liquid hydrogen to ambient temperature hydrogen gas using water as the heat source. In a previous paper  results were presented from a scale model H2O-LH2 heat exchanger built and tested at this laboratory. During the past year heat transfer was studied in the small model incorporating a twisted tape swirl inducer and in 2 passes (160 ft) of the 4.06-in. ID full-scale unit. The results of both these investigations are discussed herein.
