| | Section | Purpose and Key Calculations/Equations | Key Inputs | | :--- | :--- | :--- | :--- | | 1 | Gas Properties | Define gas properties at inlet conditions. Use ideal gas law to adjust density for temperature and pressure if needed. | Temperature, Pressure, Flow Rate, Gas Viscosity, Density | | 2 | Particle Properties & Required η | Calculate required target efficiency. | Particle Diameter, Particle Density, Inlet & Outlet PM Concentration | | 3 | Liquid & L/G Ratio | Determine liquid flow rate, choose optimal L/G ratio, and set liquid properties. | Liquid Density, Viscosity, Surface Tension, L/G Ratio (e.g., 0.5-2.5 L/m³) | | 4 | Throat Design | Calculate critical throat dimensions and other parameters. Use dl = (0.000585/vr) √(σ/ρl) + 0.0597 (µl/√(σ/ρl))^0.45*(Ql/Qg)^1.5. | Throat Velocity (e.g., 60-120 m/s), Throat Diameter, Droplet Sauter Mean Diameter (dl) | | 5 | Efficiency & ΔP Models | Implement core performance equations (Johnstone for η, Hesketh for ΔP). Use ψ = C dp² ρp vt/(9 µg dl). Use η = 1 − e^(-k R*√ψ). | Inertial Impaction Parameter (ψ), Cunningham Correction Factor (C), Johnstone 'k' (0.1-0.2) | | 6 | Output & Optimization | Provide key results (η, ΔP) and allow 'what-if' analysis. Add a 'Design Goal' to solve for vt or L/G. | - |
