PARADVECT (PARticle ADVECTion): a Python code to simulate the trajectory of particles advected by a fluid flow

Direct interception or inertial impaction? A theoretical derivation of the efficiency power law for a simple and practical definition of capture modes

“…( 21), we simulate the advection of particles having diameter ratios 0.008 ≤ R ≤ 0.1 in fluid flows at Reynolds numbers 3 ≤ Re ≤ 300 around a circular collector, following the same methodology described in Boudina et al 26 In brief, we perform two-dimensional DNS with CADYF, 27 an in-house monolithic finite element solver. Then we export the flow solution into PARADVECT, 28 a Python code that integrates the momentum equation of each particle. This latter is subjected to hydrodynamic drag, pressure load, and added mass force.…”
