Twenty-Third Symposium on Thermophysical Properties

Estes Park,CO
June 27th–July 2nd, 2027

Organized By:
National Institute of Standards and Technology
Joint ASME-AIChE Committee on Thermophysical Properties

About the Conference

This conference jointly represents the Twenty-Second Symposium of the well-established series of conferences on thermophysical properties and the eighteenth in a series of conferences organized by the International Association for the Properties of Water and Steam (IAPWS). The Symposium is concerned with theoretical, experimental, simulation, and applied aspects of the thermophysical properties of gases, liquids, and solids, including biological systems. ICPWS is focused on the properties, science, and applications of water, steam and aqueous systems, primarily as needed for the electric power generation community and within climate science. Appropriate topics are:


Thermodynamic Properties

including equation of state, phase equilibria, p-V-T behavior, heat capacity, enthalpy, thermal expansion, sound speed, and critical phenomena.

Transport Properties

including thermal and electrical conductivity, viscosity, mass diffusion, thermal diffusion, non-Newtonian behavior, and thermal, thermoacoustic, and other diffusion waves.

Optical and Thermal Radiative Properties

including dielectric constant, refractive index, emissivity, reflectivity, and absorptivity.

Interfacial Properties

including solid-solid interfaces, surface tension, interfacial profiles, interfacial transport, and wetting.

Data Correlation

including data evaluation and prediction, standard reference data, databases, and storage and retrieval of thermophysical-property data.

Power Cycle Chemistry

including related aqueous physical chemistry for power generation involving water and/or steam in fossil, nuclear, or renewable contexts.
