This is the Symposium of the well-established series of conferences on thermophysical properties. The Symposium is concerned with theoretical, experimental, simulation, and applied aspects of the thermophysical properties of gases, liquids, and solids, including biological systems. 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.

• Correlations, Databases, and Engineering Equations of State
  Eric Lemmon, NIST
  Roland Span, Ruhr-Universität Bochum
  

  This session deals with equations of state, correlations, or empirical models that can be used to calculate thermophysical properties of fluids or mixtures. Examples are Helmholtz energy based equations, cubic equation of state, BWR pressure explicit equations, corresponding states models, transport models, vapor pressure correlations, spline interpolations, estimation models or calculation methods for vapor-liquid equilibrium or solubilities, and surface tension correlations. Other topics might include fitting techniques, or group contribution methods.

• Fluid Property Measurements
  Diego Cristancho, Dow Chemical
  Ala Bazyleva, NIST
  

  The sessions on Fluid Property Measurements are a forum for reports of experimental studies of thermophysical properties in broad ranges of pressure, temperature, and composition, including safe handling of toxic and corrosive compounds. Emphasis should be placed on the industrial relevance of the results and/or their scientific significance to better understand molecular interactions, to advance property models and databases, or to benchmark force fields and simulation results. The topic, scope, and style of the presentations should fit the broad audience of these sessions.

• Instrumentation and Measurement Techniques
  Tom Bruno, NIST

  A major strength of diffusion-wave methodologies is their ability to perform depth profilometry in inhomogeneous matter thereby giving rise to the inverse problem. For example, with thermal-wave diagnostics, thermophysical property depth profiles can be reconstructed. Further inverse problem theme areas include imaging and tomography. Sessions dedicated to these topics will highlight contributions in the mathematical methods of the diffusion-wave inverse problem, computational tools and scientific / engineering implementation of methods toward thermophysical, optical and acoustic/ultrasonic properties.

  The sessions on non-equilibrium thermodynamics will focus on recent advances highlighting the applicability of theoretical methods to investigate transport phenomena (heat, mass, charge transport in bulk and under confinement conditions) and dissipation processes, non-equilibrium modeling/simulation techniques and experimental studies under non-equilibrium conditions.

• Optical and Thermal Radiative Properties
  Zhuomin Zhang, Georgia Tech
  Leonard Hanssen, NIST
  

  Optical and thermal radiative properties of advanced materials are critically needed for energy conversion systems, thermal management, microelectronics, materials process and manufacturing, and non-contact temperature measurement. This focused topic will provide a forum for participants to present the most recent research results on all aspects of measurement, theory, simulation, and modeling of emittance, absorptance, reflectance, transmittance, and scattering properties of surfaces, thin films, particles, periodic and aperiodic structures and composites.

  This session solicits contributions related to the thermophysical properties of polyamorphic fluids.“Fluid polyamorphism” is the existence of two alternative amorphous structures in a single-component fluid. Liquid/fluid polyamorphism is found in a broad group of very different materials, including silicon, silicon dioxide, germanium, phosphorous, sulfur, cerium, and hydrogen, usually at extreme conditions For example, the transition between metallic and nonmetallic hydrogen is expected at the pressures of several hundred million bars. This phenomenon is also hypothesized in metastable, deeply supercooled water. The session welcomes contributions from experimental, theoretical, and computational studies of thermophysical properties of polyamorphic systems.
