Special Issue Information

Dear Colleagues,

The behaviour of nearly critical fluids, the physical singularity of matter, is fascinating and of interest to the engineering community. Power generation using supercritical CO2 technology is attracting attention as an innovation that can contribute to the global energy crisis by making a more efficient system. However, supercritical CO2 systems that actively exploit the rapid changes in properties near the criticality are still largely unexplored and require active research and development.

This Special Issue aims to present and disseminate the most recent advances related to the theory, design, modelling, application, control, and condition monitoring of all types of near-critical CO2 power conversion system.

The topics of interest for publication include, but are not limited to:

  • All aspects of supercritical CO2 systems;
  • Novel applications of near-critical CO2 systems;
  • Control logics for supercritical CO2 systems;
  • Operation and maintenance technologies for supercritical CO2 systems;
  • Advanced modelling approaches;
  • Optimal design methodologies;
  • Numerical analysis methodologies.

This work presents the development and validation of an enthalpy-based implicit continuous Eulerian (ICE) solver, termed the near-critical ICE solver (NICES), for the analysis of near-critical CO2 thermodynamic systems. Traditional approaches relying on pressure and temperature as main inputs for the analysis have limitations in handling CO2 near the critical point, which exhibits unique characteristics and frequent phase changes. To overcome these limitations, this study proposes using enthalpy as a more suitable mathematical modeling approach. The NICES methodology employs the homogeneous equilibrium model and the Span and Wagner equations of state for CO2. This solver demonstrates improved numerical stability and computational speed compared to explicit calculation methods, as validated by frictionless heated pipe scenarios involving phase transitions near the critical point. The enthalpy-based NICES platform can predict thermohydraulics, including multiphase flows, without requiring specialized two-phase flow models. Full article
