Sažetak
In this paper solid particles erosion prediction in an elbow geometry is made by means of numerical simulation. The corresponding, three-dimensional numerical simulations are carried out with the Ansys Fluent software package. The continuous phase is simulated with the Reynolds Stress Model (RSM), which belongs to the group of Reynolds Averaged Navier Stokes (RANS) models. Discrete particle paths are traced in Lagrangian reference frame. Additional sub-models are implemented into the software in order to properly resolve the particle movement through the wall-bounded geometry. These sub-models include particle-wall collisions and erosion. Proper resolving of particle-wall collisions is crucial for pneumatic transport simulations, as it makes the strongest influence on the particle history, concentration and velocity components prior to the place of interest (elbow erosion in this case). The removal of wall material due to erosion (erosion rate) is calculated using the Finnie’s model of erosion developed for ductile materials. Simulation results were validated with the published experimental data from [1].
