Venturi scrubber (wet) simulation

gas + solids + scrubbing liquid -> clean gas + slurry

Governing equations

The exact equations the solver works for a venturi scrubber (wet) — the same math shown in the app's "Theory" panel, not a black box.

$\Delta P$

throat pressure drop [Pa]

$\rho_L$

scrubbing-liquid density [kg/m³]

$Q_L, Q_G$

liquid and gas volumetric flows [m³/s]

$v_{gt}$

throat gas velocity [m/s]

$\eta$

particulate collection efficiency [0..1]

$d_{pc}$

aerodynamic cut diameter — 50% collection [m]

$d_{eff}$

shape-corrected effective particle size [m]

$\varepsilon$

gas-removal efficiency for a soluble species [0..1]

Parameters

throat_velocity_m_s [default 60], cut_diameter_m [aerodynamic 50% cut, default 1e-6], liquid_molar_mass_kg_mol [default 0.018 water], liquid_density_kg_m3 [default 1000]; optional gas absorption: soluble_components [list], gas_removal_efficiency [0..1, default 0]
