Abstract
AbstractMeasurements were made of the concentration of particles in a horizontal transport pipe using an optical probe. The distribution of particles over the pipe cross‐section was measured. Particle transport in a horizontal two‐dimensional (2‐D) channel was simulated using an Eulerian two‐fluid model. A model is proposed for the turbulent dispersion of particles and implemented in the two‐fluid model. The turbulence in the gas phase is modeled using a modified k − ϵ model that accounts for the influence of the particles on the gas‐phase turbulence. Comparisons with measurements of air‐particle flow in a horizontal pipe show qualitative agreement between measurements and calculations. © 2005 American Institute of Chemical Engineers AIChE J, 2005
