Special Issue Information

Dear Colleagues,

The objective of this Special Issue is to deliver predictors to control transport phenomena in energy systems to improve their overall performance and efficiency. Innovative contributions apply entropy and exergy-based methods to gain insight into multiphase flows with heat transfer. This research involves the parallels between momentum, energy, and mass transport with respect to entropy and the Second Law of Thermodynamics. The publications in this Special Issue will contribute to advancing energy systems globally and providing innovative methods to address the energy crisis.

Authors are invited to submit their original work and survey papers for publication in this Special Issue of Energies. Topics of interest for this Special Issue include, but are not limited to:

  • Analytical and experimental studies in transport phenomena;
  • Energy systems performance improvement investigations;
  • Hydrogen production methods;
  • Battery thermal management studies.

We look forward to receiving your contributions. It is recommended to send a tentative title and a short summary of the manuscript to Energies Editor Ms. Carly Liu <[email protected]>.

Dr. Ofelia A. Jianu
Guest Editor

Hydrogen extraction from nature is a time-consuming and energy-intensive procedure. Most of the current methods of extracting H2 are not eco-friendly, and the thermochemical copper-chlorine (Cu-Cl) cycle is a promising alternative since the ingredients are continuously recycled within the cycle without discharging pollutants into the atmosphere. In this study, the heat recovered from molten cuprous chloride (CuCl) salt produced in one of the reactors and quenched in a water bath is analyzed numerically to determine the amount of thermal energy that can be recovered and improve the efficiency of the Cu-Cl cycle. The quenching cell is simulated in an inert atmosphere since CuCl is highly reactive in the presence of oxygen. The interactions of various diameters of CuCl droplets within nitrogen (N2) are numerically modeled in COMSOL Multiphysics. Silver chloride (AgCl) is also used in this study to validate the phase-change process. It was discovered in this study that during the free fall, the outer surface of the molten droplets solidifies, and the phase change of droplets slowly propagates radially inwards, which slows down the energy dissipation. It was also determined that the average internal temperature of the droplet does not change substantially with droplet diameter or quenching height. Based on this study, the net energy recovered after quenching was calculated to be around 23 kJ during 1 kg of H2 production. Full article
