Swift Thermoacoustic Formulation:
• Thermal Penetration Depth: δκ = √(2 k / (ρ cp ω)) [mm]
• Optimal Stack Spacing: y₀ ≈ 2 - 4 δκ
• Acoustic Power Work: Ẇ₂ ∝ Astack · δκ · ω · p₁² / (ρ a²)
• Coefficient of Performance: COP = Q̇c / Ẇ₂

📘 Calculation Methodology & Thermoacoustic Standards
Thermoacoustic Heat Pumping Effect
Oscillating gas parcels experience cyclical compression, displacement, and thermal relaxation with the solid stack wall, pumping heat from the cold heat exchanger (CHX) toward the hot heat exchanger (HHX).
No Moving Parts & Noble Gas Operation
Eliminates pistons, valves, and synthetic fluorinated refrigerants. Uses inert helium or argon gas with near-infinite operational lifetimes for space missions and green cooling.
Key Engineering Assumptions
- Linear Rott acoustic standing-wave approximation ($D_r \le 10\%$).
- Short-stack approximation with parallel plate stack matrix.
- Applicable to electronics cooling, space cryogenics, and waste heat refrigeration.
