摘要：

Deposition velocities of glass-fiber particles of 1-2-mu-m 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 less-than-or-equal-to 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.
