Real gas effects in condensing nozzle flows are discussed by the virial equation of state truncated after the second virial coefficient. The thermal choking conditions in nozzles previously derived for a perfect condensible vapor are generalized to include real gas effects. For these cases it is shown that the critical amount of heat necessary to thermally choke the flow can be defined explicitly only for the expansion of a pure vapor. © 1994 Birkhäuser Verlag.
