15 صفحه اولLes of Gas-particle Turbulent Channel Flow (the Effect of Inter-particle Collision on Structure of Particle Distribution)
Particle dispersion in a fully-developed turbulent flow was studied. Numerical simulations with two-way coupling were performed for downward particle-laden turbulent flows in a vertical channel. Fluid turbulence was calculated by using LES, while the particle motion was treated by Lagrangean approach. In addition, inter-particle collision was taken into consideration. In this work, we focused o...
متن کاملNumerical simulation of particle-laden turbulent channel flow
This paper presents results for the behavior of particle-laden gases in a small Reynolds number vertical channel down flow. Results will be presented for the effects of particle feedback on the gas-phase turbulence and for the concentration profile of the particles. The effects of density ratio, mass loading, and particle inertia will be discussed. The results were obtained from a numerical sim...
متن کاملLarge-eddy Simulation of a Particle- Laden Turbulent Channel Flow
Large-eddy simulations of a vertical turbulent channel flow with 420,000 solid particles are performed in order to get insight into fundamental aspects of a riser flow. The question is addressed whether collisions between particles are important for the flow statistics. The turbulent channel flow corresponds to a particle volume fraction of 0.013 and a mass load ratio of 18, values that are rel...
متن کاملPoint-Particle DNS and LES of Particle-Laden Turbulent flow - a state-of-the-art review
Particle-laden or droplet-laden turbulent flows occur in many industrial applications and in natural phenomena. Knowledge about the properties of these flows can help to improve the design of unit operations in industry and to predict for instance the occurrence of rain showers. This knowledge can be obtained from experimental research and from numerical simulations. In this paper a review is g...
