摘要

Use of empirical correlations for state variables allows for more accurate physical representation than simplistic approaches offer. The simplistic approaches include the ideal or stiffened gas laws, both of which can have major shortcomings. This is particularly important when dealing with cases that are near saturation or where liquid compressibility is important. Hence, two new state variable libraries have been developed. The first is called Quicksteam, which is for water and steam, and the second is called Quickmethane, which is for methane liquid and vapour. Well established correlations of experimental data have been used to create the libraries.
