- Correlations,
Databases, and Engineering Equations of State
Eric Lemmon, NIST
Monika Thol, 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
Tara Fortin, NIST
Markus Richter, Technische Universität Chemnitz
This session will focus only on contributions reporting novel
experimental techniques or instrumentations, either not yet published,
or published within the past 12 months. The focus is on the
development of new techniques. Contributions made with established
apparatus should be submitted to other sessions.
- Ionic Liquids
José Nuno Canongia Lopes, Instituto Superior Técnico - Lisbon
Joan Brennecke, University of Texas
Sessions in this area relate to the thermophysical properties of
ionic liquids and their mixtures and solutions. Topics of interest
include gas solubility, molecular interactions, thermal
conductivity, viscosity, diffusion, densities, excess volumes and
enthalpies, isothermal compressibilities, surface tension,
enthalpy of fusion, phase behavior, calorimetry, modeling and
simulation of ionic liquids, and ionic liquids as functional
materials.
- Molecular Simulation
Andrei Kazakov, NIST
Michael Shirts, University of Colorado Boulder
This session focuses on the use of molecular simulations to estimate
and understand thermodynamic and thermophysical
properties. Applications of molecular simulations to predict
properties of fluid and/or solid systems and to elucidate physical
phenomena are of particular interest. Other strongly encouraged topics
are new modeling and simulation methods, including
coarse-grained/multiscale approaches and analyses of error propagation
and uncertainty quantification between molecular models and physical
properties.
- Non-equilibrium Thermodynamics
Fernando Bresme, Imperial College
David Reguera, University of Barcelona
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
Liping Wang, Arizona State University
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. Reports on the state-of-the-art theories and methods in modeling, designing, fabricating, and testing micro/nanostructures to tailor the radiative properties in both the far field and the near field will be welcomed.
- Properties for Materials Science at High Temperatures
Doug Matson, Tufts University
Gernot Pottlacher, TU Graz
These sessions will concentrate on experimental and theoretical
aspects for the measurement of thermophysical properties of materials
at high temperature. Measurement timescales span the continuum from
highly non-equilibrium subsecond thermophysics to quasi-static and
equilibrium techniques used for identification of properties for
metallurgical process design.
- Properties of Aqueous Systems
Andre Anderko, OLI Systems
Simona Lago, INRiM
We seek papers about the measurement, theory, and correlation of
thermophysical properties of aqueous systems, including solutions of
electrolytes and nonelectrolytes in water. In addition to fundamental
studies of thermodynamic and transport properties, we encourage papers
that relate the properties of aqueous solutions to applications such
chemical process design, geochemistry, oceanography, water treatment,
power generation, hydrometallurgy, materials science, electrochemical
energy sources, life sciences, and protection of the environment.
- Properties for Fuels and Energy Systems
Sergio Quiñones-Cisneros, Ruhr Univ. - Bochum
Kurt Schmidt, Schlumberger Technology Corporation
These sessions deal with thermophysical properties of fuels including
natural gas, petroleum-based fuels, coal-based fuels, oil sands, shale
gas, and gas hydrates. Also of interest are properties of systems
related to carbon capture and sequestration as well as gas
injection. Past sessions have included viscosity, density,
calorimetry, phase behavior, fuel and oil characterization, thermal
conductivity, and thermal degradation. Experimental, modeling, and
simulation studies are all encouraged.
- Properties of Polymers
Nic Rorrer, NREL
Anthony Kotula, NIST
These sessions focus on measurements, theories, and simulations of
properties of polymeric systems and materials. While any new concepts
pertaining to the properties of polymers are welcomed, specific
interests include new methods of measurement such as nanocalorimetry,
systems of growing interest such as charged and ion-containing
polymers, and new developments in age-old problems such as
polymer/polymer and polymer/solvent interactions.
- Properties of Solids
Heng Ban, University of Pittsburgh
Ursula Kattner, NIST
Sessions in this area are devoted to the thermophysical properties of
solids. Topics of interest include but are not limited to thermal
properties of solids, thermodynamic studies of phase transitions, and
thermal deformation. We seek papers using experimental, theoretical
and/or computational methods in fundamental research and/or
applications in areas such as energy, environment, industrial
processes and life sciences.
- Properties of Working Fluids including Refrigerants
Mark McLinden, NIST
Stephanie Outcalt, NIST
Papers reporting experimental measurements or models for the
properties of fluids intended as working fluids in thermodynamic
cycles are solicited. This would include thermodynamic and transport
properties, equations of state and other models, pure fluids and
mixtures. Working fluids for refrigeration and power cycles are of
interest. Data and models for the "new" low-GWP refrigerants and
working fluids for organic Rankine cycles are particularly
welcome. Papers comparing one cycle versus another or one fluid versus
another in a particular cycle are generally not of interest, unless
the focus is clearly on the property characteristics.
- Theory of Thermophysical Properties

This session focuses on the use of molecular theory to predict
thermophysical properties, including molecular based equations of
state, classical density functional theory, and first principles based
approaches.

Xinwei Wang, Iowa State University
Yangsu Xie, Shenzhen University
This session will cover wide-spectrum research related to
thermophysical properties of nanostructured materials (including
nanofluids). Examples include, but not limited to, thermal properties
of novel nanostructured materials (quantum dots, nanowires, thin
films, graphene, carbon nanotubes and their composites), new
technology development to explore the thermal transport behavior of
nanostructured materials, effect of material structure on
thermophysical properties, and theoretical investigation and computer
modeling to look into the physics underpinning thermal transport in
nanostructured materials.
- Properties of Metastable and Glassy Systems
Frédéric Caupin, Lyon University
Metastability covers here all conditions beyond the usual stability boundaries of a phase, in which equilibrium can still be reached for a finite time; this includes e.g. supercooled and superheated liquids, supersaturated solutions, metastable polymorphs of crystals... These states play a key role for our understanding of phase transitions, as well as in natural phenomena and industrial applications. The sessions will highlight the original experimental strategies (e.g. small and/or container-less samples, ultrafast techniques...) that are implemented to prepare materials and measure their thermodynamic and dynamic properties under these challenging conditions. The specific case of supercooled liquids has a strong connection with the glass transition, involving complex dynamic phenomena (relaxation time, dynamic heterogeneity, ageing...). Reports on emerging experimental topics in this field are welcome.
