📘 Calculation Methodology & Supercritical CO2 Standards
Pseudo-Critical Property Variations
Near the pseudo-critical line ($T_{pc}$), $CO_2$ undergoes dramatic non-linear spikes in specific heat ($c_p$) and shifts in density, providing exceptionally high heat exchange rates without boiling/pinch limitations.
High-Pressure Brazed Plate Compactness
Chevron corrugated vacuum-brazed stainless steel plates provide compactness exceeding $1000\,\text{m}^2/\text{m}^3$ while withstanding pressures beyond $100 - 150\,\text{bar}$.
Key Engineering Assumptions
- Modified Jackson & Hall supercritical Nusselt correlation for chevron BPHEs.
- Counter-current gas cooling without condensation phase change.
- Used in transcritical $CO_2$ heat pumps, R744 supermarket refrigeration, and $sCO_2$ Brayton power cycles.
