Determination of Separation Efficiency in Wire Mesh Mist Eliminator by CFD

On the assumption of the staggered array model, a numerical simulation of the vapor flow field in wire mesh mist eliminator along with the mechanism for droplet capture due to inertial impaction is presented in this paper. The efficiency of a single wire in the eliminator is computed in order that the efficiency of wire mesh mist eliminator can be calculated. The obtained efficiency is found to be within a reasonable agreement with the published literature data. The effect of wire diameter, pad thickness, packing fraction on the separation efficiency and the relation between Stk and the efficiency of a single wire is investigated.
