Full TextAbstract
In this paper the effect of dispersion in turbulent two phase (gas-solid) flow on trajectory of particles in cyclone separators and the efficiency has been investigated. To predict flow field in cyclone simpler algorithm was used to solve Eulerian equations. Algebra stress model (ASM) solves the Reynolds stress in momentum equations and the dispersion of fluid velocity is simulated by the use of a stochastic Lagrangian model. Results show with increasing particles diameter, the dispersion effect is decreased. Also it is obvious that dispersion makes the separation efficiency decreased.
