Abstract
The moisture separator reheater (MSR) is a facility which is used to improve the thermal efficiency for the nuclear power plant. We have been developing the technique to improve moisture separation efficiency of MSR using wire-mesh combined with wave-shaped vanes. The goal of this study is to clarify the wire-mesh configurations which can minimize the exit moisture by droplet diameter measurement under a dispersed flow condition which was made by air and water from a spray nozzle. The results showed that droplet diameters were increased as the number of layer was increased. Within our experiment range, the wire-mesh configuration which has more than three layers yields the increase of the droplet diameter. Besides, although the increasing flow velocity caused generation of small droplets, it was indicated that the velocity range which keeps droplets coarse, can expand using means of increasing layer of the mesh.
