Abstract：Compared with normal multiphase turbulent flow,charged multi-phase turbulent flow appears more complex due to the coupling between electric field and flow field.How to describe the coupling action with mathematic function and to model it are the main task in charged multi-phase turbulent flow.Based on the establishment of single-phase charged fluid turbulence model and charged particles pseudo-fluid multi-phase turbulence governing equations,a new simulation model was deduced with the double fluid modeling method regarding the charged particle phase as a fluid phase.In this model,the coupling action between turbulent flow field and electric field was described with electric conjunction term and this term will be modeled by using an electric-turbulence exchanging coefficient.This model could be applied in the accurate engineering simulation of big size complex charged multi-phase turbulent flow.
