Special Issue Information

Dear Colleagues,

We trust this email finds you well. It is our pleasure to invite you to submit an article for an upcoming Special Issue of Energies (IF = 2.702) entitled “Thermophysical Properties of Working Materials for Power Engineering”, which will be focused on the thermodynamic and transport properties of working materials for energy-generating systems, including renewable energy. In this Special Issue, we aim to highlight new experimental data and modeling of the thermophysical properties at low, ambient or high temperature conditions, as well as at ambient or high pressure conditions of working materials including fluids, nanofluids, ionic liquids, ionanofluids, oils, natural gas, and solids for power engineering.

If you plan to submit an article, please respond to [email protected] or [email protected] by 30 June 2021. Once you accept this invitation, you will be notified via e-mail about how to access the journal’s online manuscript submission and review system.

Submissions should comply with the Energies guidelines for authors. Please note that the usual peer review process will be applied.

Thermophysical properties of HFE-356mmz in the vapor phase were measured by means of an acoustic-microwave resonance method. HFE-356mmz, which is 1,1,1,3,3,3-hexafluoro-2-methoxypropane in chemical name, is expected to be used as a working fluid with low global warming potential for the Organic Rankine cycle (ORC). The sound velocity and dielectric permittivity were simultaneously measured by using a cylindrical acoustic-microwave resonator. The sound velocity data were analyzed to obtain the ideal-gas heat capacity at constant pressure. The integral of the ideal-gas heat capacity as a function of temperature derives the ideal-gas enthalpy, which is a fundamental and important energy property to simulate the thermodynamic cycle. Similarly, the analysis of the dielectric permittivity data leads to information on the ideal-gas molar polarizability, dipole moment, and density. The acquired thermophysical properties of HFE-356mmz were compared to those of R-245fa and n-pentane, which are the existing working fluids for the ORC system, to prospect a feasibility of HFE-356mmz as their alternative.

1-Butanol can be considered as a good fuel additive, which can be used at high pressures. Therefore, the knowledge of high-pressure thermophysical properties is crucial for this application. In this paper, new experimental data on the speed of sound in 1-butanol in the temperature range from 293 to 318 K and at pressures up to 101 MPa are reported. The speed of sound at a frequency of 2 MHz was measured at atmospheric and high pressures using two measuring sets operating on the principle of the pulse–echo–overlap method. The measurement uncertainties were estimated to be better than ±0.5 m·s−1 and ± 1 m·s−1 at atmospheric and high pressures, respectively. Additionally, the density was measured under atmospheric pressure in the temperature range from 293 to 318 K using a vibrating tube densimeter Anton Paar DMA 5000. Using the experimental results, the density and isobaric and isochoric heat capacities, isentropic and isothermal compressibilities, isobaric thermal expansion, and internal pressure were calculated at temperatures from 293 to 318 K and at pressures up to 100 MPa.
