NUMERICAL MODELING OF FINE PARTICLE FRACTAL AGGREGATES IN TURBULENT FLOW
ABSTRACT
A method for prediction of fine particle transport in a turbulent flow is proposed, the interaction between particles and fluid is studied numerically, and fractal agglomerate of fine particles is analyzed using Taylor-expansion moment method. The paper provides a better understanding of fine particle dynamics in the evolved flows.
