Abstract :
Thermodynamic properties of NaK of arbitrary composition are estimated, for the first time, from information on Na and K in data banks, in three regions: under the vapor dome, in the superheated region and in the subcooled region. A computer program accepting various input pairs is now available. An extensive parametric study has been carried out by the present author using this program. Several possible design points for an NaK-78 (78.4% K) Rankine-cycle vapor turbine, with and without mechanical moisture removal, are presented as examples illustrating the use of the database
