Overview

Numerical investigation demonstrates improved heat transfer in gas coolers with fins, indicating efficiency gains in CO2 systems.

Key Points

  • Fins integrated into channel sidewalls significantly enhance the heat transfer performance of supercritical CO2.
  • The study found that the heat transfer coefficient increases with mass flux, indicating better performance under higher flow rates.
  • Three-dimensional numerical models were developed, accounting for complex factors like buoyancy and entrance effects.
  • Enhanced heat transfer was observed, with performance improvements of 1.85–2.15 for aligned fins compared to smooth channels.
