Detailed Description

A class for thermal conductivity model that is defined by The International Association for the Properties of Water and Steam IAPWS (File accessed at 13.01.2023) - (Daucik and Dooley, 2011)

With the definition, the thermal conductivity is a function of temperature and water density

Attention: The critical enhancement, \(\bar{\lambda}_2\), is not considered. For information on region of significance and the significance, please see Figure 2 from the document linked in the upper paragraph.
