About The Conference

This is the Eighteenth 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.
• 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.

• Correlations 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.

• Databases and Software
  Ken Kroenlein, NIST
  Richard Rowley, BYU
  

  Thermophysical property databases provide core information for process modeling and development. The breadth, accuracy, currency and reliability of the data as well as the integrity and management of the database itself are important factors in the ultimate reliability of the modeled process. In addition to these topics, papers appropriate for this session might include issues associated with database management systems, types of data, uses of databases, the handling of large quantities of data, database procedures, data quality and estimates of reliability, data uncertainties, thermophysical property evaluation, data traceability, database quality control, and error detection/prevention. Topics related to database software and the use of databases for development of property prediction techniques are also invited for this session. Topics in this area might include software for retrieval, analysis, and display of data; expert systems; automated data evaluation; and techniques such as data mining and QSPR methods that rely on the strengths of the database.

  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.

  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.

Applications include small and confined systems, interfacial non-equilibrium phenomena, and biological systems.

• 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 noncontact 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.
