Large eddy simulations of gas-particle turbulent round jet flows

Xilin Wang

Abstract

Two-way coupled large eddy simulations (LES) were used to study the influence of dispersed particles on the gas-phase jet in gas-particle turbulent round jet flows. The single-phase jet shape and statistical properties including the streamwise velocity and turbulent intensity from the simulation agree well with experimental results for single-phase and gas-particle flows. The LES results for the two-phase jet flow show that 105 μm diameter particles act as a damp in the flow which suppresses the turbulence intensity.
