Thermal equation of state BWR for water and water steam

Abstract

The fundamental bases for the calculation of the thermodynamic properties of substances are the thermal equation of state and the dependence of some of the basic specific heat capacities on temperature. Any other thermodynamic properties of a substance can already be deduced from these relations. The aim of this paper is to design the simple thermal equation of state for water steam based on original BWR thermal equation of state, which describes the behavior of H2O in the gaseous phase in region of usual pressures and temperatures with sufficient accuracy.
