Cyclone simulation

gas + solids -> clean gas + captured solids

Governing equations

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

$d_{50}$

cut size [m] — the diameter collected with 50% efficiency; the headline number

$\mu$

gas viscosity [Pa·s]

$W$

inlet width [m]

$N_e$

effective number of gas turns inside the cyclone

$v$

inlet gas velocity [m/s]

$\rho_p, \rho_g$

particle and gas densities [kg/m³]

$\eta$

collection efficiency [0..1]

$d_{eff}$

effective particle diameter

$d$

particle diameter [m]

$\psi$

shape factor

Parameters

velocity [m/s inlet, default 15], diameter [m body, default 0.5]; optional n_turns, gas_viscosity, particle_density [kg/m^3], gas_density [kg/m^3]; the feed's solids.sphericity (default 1.0) lowers efficiency for non-spherical particles
