In this paper, separation of water droplets from air including water droplets by eliminators is investigated through experiments. Eliminators used here are constructed by zigzag bended thin-plates of a similar shape, which are held parallel to the air particle flow direction and which have a dimensionless pitch of 0.75. Moreover, the plates have two different bending angles, one is 90° while the other is 60°. Furthermore, the former plate has bending numbers of 1, 2, 4 and 6 respectively while the later plate has bending number of 4. For all of the eliminators mentioned above, mean air particle velocity is varied over the range of 0.5 to 7.0 m/s, with the size of water droplets being varied over the range of 5 to 190μm. The separation efficiencies of these eliminators are sufficiently in good agreement with those predicted by theoretical analysis which has been presented by the authors of this paper. Characteristics of size distribution of water droplets at the inlet and the outlet to the eliminator and furthermore resistance coefficients of these eliminators are also investigated.
