Solar Ejector Refrigeration Formulation:
• Entrainment Ratio: ω = ṁsec / ṁpri ∝ √[(Tg−Tc)/(Tc−Te)]
• Thermal COP: COPth = Q̇cool / Q̇solar_gen
• Required Solar Area: Asolar = Q̇gen / (G · ηcoll) [m²]
• Completely compressor-free thermal refrigeration.
• Entrainment Ratio: ω = ṁsec / ṁpri ∝ √[(Tg−Tc)/(Tc−Te)]
• Thermal COP: COPth = Q̇cool / Q̇solar_gen
• Required Solar Area: Asolar = Q̇gen / (G · ηcoll) [m²]
• Completely compressor-free thermal refrigeration.

📘 Calculation Methodology & Solar Ejector Standards
Supersonic Jet Entrainment
High-pressure motive vapor expands through a convergent-divergent nozzle to supersonic speeds ($M > 2$), creating a low-pressure zone that sucks vapor from the evaporator.
100% Thermal Drive (No Compressor)
Solar thermal energy directly powers the cycle. Only a tiny liquid feed pump is required, consuming less than $1\%$ of the electrical energy of vapor compression chillers.
Key Engineering Assumptions
- 1D gas dynamic model of supersonic constant-pressure mixing.
- Saturated vapor conditions at generator and evaporator exits.
- Applicable to solar air conditioning, industrial steam ejectors, and food cold storage.
