Abstract

This paper describes an autonomous computer package, called HTWOO, which comprises of 24 subroutines linking up 16 of the most important thermodynamic and transportation properties of steam & water. The Helmholtz free energy function is used as the fundamental equation from which expressions for all the other thermodynamic properties can be derived by partial differentiation. The package permits determination of any property provided the corresponding state point is specified by any two of the five following properties: temperature, specific volume, pressure, enthalpy and entropy. The paper outlines the potential of the HTWOO package, describes the structure and the terminology followed and explicits the rationale behind the computational algorithms used. The computer package is written in FORTRAN and can be exploited on any average sized microprocessor.
