Simulation of particle trajectories in bifurcating tubes (Q1316003)

A numerical method for computing aerosol particle trajectories in bifurcating tubes has been elaborated. The model consists of three characteristic parts: (i) construction of the geometry of the bifurcation, (ii) calculation of the fluid flow field, and (iii) computation of the particle trajectories. The geometry was designed on the three-dimensional computer mesh. The flow field was formulated by solving the steady-state Navier-Stokes and Poisson equations with a finite difference approximation.
