Development of an explicit Eulerian method for treating particle-laden turbulent flow in dust collectors

Prediction of particle removal efficiency in all kinds of dust collectors includes mathematical modeling of particle-laden flow. one of the main problems for such modeling is to find particle velocity distribution which can be predicted using a particle momentum balance equation. a common simple alternative is to use equilibrium or settling velocities. in this work, a comprehensive mathematical model for particle removal in double-stage electrostatic precipitators was developed. analysing the results of this model shows that the equilibrium assumption can be considered as a reliable method for a stokes number less than 0.001. also, for a higher stokes number, an explicit eulerian method was developed for the evaluation of particle velocities explicitly. this method eliminates solving particle momentum balance equations which is a relatively time-consuming step in mathematical modeling of dust collectors.
