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 equations of state, 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.

Non-invasive breath analysis has the potential to revolutionize health monitoring and disease diagnosis. However, the thermophysical foundations for breath analysis are not well established. In these sessions, we welcome presentations that shed light on any aspect of breath analysis via measurement or modeling. This includes the design and performance of sampling devices, fluid dynamics of the human airway, properties or concentrations of biomarkers, the complex equilibria responsible for a molecule’s presence in exhaled breath, vapor-liquid equilibria of volatile organic compounds in breath aerosols, and standards development.

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.

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.
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 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. Reports on the state-of-the-art theories and methods in modeling, designing, fabricating, and testing micro/nanostructures to tailor the optical and radiative properties in both the far field and the near field will be welcomed.
The sessions dedicated to these topics involve advanced optical-to-thermal and optical-to-acoustic/ultrasonic analytical experimental and theoretical methodologies developed and utilized for thermophysical property measurements in all states of matter. Reports in PT and PA methodologies and their applications are solicited.

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.
This session focuses on metastability and nucleation in water and aqueous systems. Topics of interest include: supercooled, superheated and stretched liquid; subcooled vapor; supersaturated solutions; metastable polymorphic crystals. We also seek works on nucleation of droplets, bubbles, crystals and clathrate hydrates; amorphous ices and aging; and other properties and processes related to phase transitions in aqueous systems.
These sessions focus on experimental measurements, theories, and simulations of the properties of polymeric materials. While any concept about polymer properties is welcomed, specific interests include the interfacial behavior of polymers, new developments in multi-modal measurement techniques, and systems such as block copolymers, nanocomposites, fibers, and thin films. Topics that have relevance to sustainability and human health are highly sought after.

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.

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; this would include fluids with boiling points higher than typical refrigerants. 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.
Clare McCabe, Heriot Watt University
This session focuses on the use of molecular theory to predict thermophysical properties, including molecular based equations of state, classical density functional theory, first principles and machine-learned based approaches.

This session will cover a wide spectrum of research on thermophysical properties of nanostructured materials. Properties of interest include (not limited to) thermal conductivity, diffusivity, specific heat, interface thermal resistance, and energy carrier dynamics. Both nanoscale and nanostructured materials are covered, with examples spanning quantum dots, nanowires/tubes, thin films, 2D materials, their composites, and nanofluids. New technology developments are also welcome in our session to push the boundaries of measurement physical scale, time resolution, and accuracy. Both experimental and theoretical investigation, and computer modeling to look into the physics underpinning thermal transport in nanostructured materials are welcome.
