Baghouse (fabric filter) simulation

gas + solids -> clean gas + captured dust

Governing equations

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

$\eta$

collection efficiency [0..1] — near-total once a cake forms

$P_t$

penetration [0..1] — the fraction that slips through (caller input)

$\Delta P$

filter pressure drop [Pa]

$S_e$

clean-fabric drag [Pa·s/m]

$K_2$

specific cake-resistance coefficient [Pa·s·m/kg]

$c$

inlet dust loading [kg/m³]

$V$

air-to-cloth face velocity [m/s]

$t$

filtration time since the last cleaning [s]

$A$

cloth (filter) area [m²]

$Q$

gas volumetric flow [m³/s]

Parameters

penetration [0..1, default 0.005 -> 99.5% capture]; sizing: air_to_cloth_ratio [m/s, default 0.02] OR cloth_area_m2; filter-drag dP: clean_cloth_drag [Pa·s/m, default 350], cake_resistance [Pa·s·m/kg, default 4000], dust_loading_kg_m3 [default 0.02], filtration_time_s [default 1800]
