: Uses established models like the Calvert cut diameter method to predict collection efficiency for specific particle sizes.

| | 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. | - | venturi scrubber design calculation xls upd

These are the same models embedded in commercial simulators. By implementing them in Excel, you gain full control, transparency, and the ability to customise the tool to your specific process. : Uses established models like the Calvert cut

Typically ranges from 60 to 150 m/s. Higher velocities increase efficiency but also increase pressure drop and energy costs. Throat Area ( cap A sub t Calculated as Critical Dimensions: Throat Length ( cap L sub t Often taken as 3 times the throat diameter ( cap D sub t Diverging Section Length ( cap L sub d | Temperature, Pressure, Flow Rate, Gas Viscosity, Density
