DEPOSITION OF NON-SPHERICAL PARTICLES (FIBRES) IN A CHANNEL WITH SUBSEQUENT BIFURCATIONS
Original language description
The article presents results from the non-spherical particle deposition in a geometrical model of part of the human airways. Particle deposition in the human airways is important subject of study. The particles in this work has been modeled using assumption of high aspect ratio of length to width. The orientation of particles is following the stream according to the forces (namely torque) implied by the fow-field. The flow is simulated by large eddy simulation (LES) using dynamic Smagorinsky sgs model.Particles are assumed rigid with a density of 1000 kg/m3 and diameter of 1e - 6 m and the length 2, 4 and 6 d. One way coupling with the continuous phase (air at standard conditions) is considered only. Comparing the deposition results with the sphericalparticles clearly shows the dependence of the deposition on the inlet boundary conditions, namely turbulence quantities. While for the computations with globular particles the velocity profile with Ornstein-Uhlenbeck fluctuation generato
