Abstract

Aerosol particles deposit onto a pipe wall in a turbulent flow, but the particles are sometimes recognized to rebound from the wall beyond a certain limit of Reynolds number, particle diameter or other parameters involved in the deposition velocity. However, there are few reports which analyze this phenomenon quantitatively. In this paper, therefore, a rebound starting point and an empirical formula for particle rebound from the pipe wall are derived, and the constants contained in the formula are determined based on the existing experimental data with particle rebound. The relations between the constants for different independent variables such as Reynolds number, particle diameter and relaxation time are also discussed.
