摘要: Abstract Two important aspects of fluid-particulate interaction in dilute gas-particle turbulent flows, namely the particle dispersion and turbulence modulation effects, are addressed using Eulerian Lagrangian modeling approaches to describe paniculate phase. Gradient diffusion approximations employed formulation while a stochastic procedure is utilized simulate formulation. The k - ϵ , model used characterize time length scales continuous phase turbulence. Models proposed for both schemes predict turbulent, fully-developed gas-solid vertical pipe flow with reasonable prediction accuracy.
