Abstract

Deposition velocities of glass-fiber particles of 1-2μm in diameter moving in air flow through a pipe, are measured for various particle sizes and flow Reynolds numbers. Experimental results indicate that for Re≤26,000 the deposition velocity is mainly affected by gravitation. Comparable experiments performed at higher Re numbers exhibit the competitive effects of turbulent fluctuations, gravitation, particle size and geometry upon the deposition velocity.
