Decay of Particle Concentration as a Function of Rotation Rate in a Rotating Drum Chamber

Abstract

Rotating drum chambers are used to keep aerosol particles suspended for an extended period of time to study aging effects. The drums are designed to rotate on a horizontal axis, using centrifugal force to counteract the effects of gravity on small particles. Theoretically, there are different rotation rates for different particle sizes that optimize suspension time. Several different methods have been used to calculate the optimal rotation rates with varying results. This report will compare these mathematical models to experimental results.
