Abstract

Deposition of silica particles onto a target is used for studying the performance of optical fiber fabrication processes. For the analysis, Falkner-Skan wedge flow is chosen as the particle laden flow. Brownian diffusion, thermophoresis, and coagulation of the particle are considered and effects of these phenomena on particle deposition are examined. A moment model is developed in order to predict distributions of particle number density and particle size simultaneously. Particle deposition with various wedge configurations is investigated for conditions selected for a typical VAD process.
