abstract

This paper presents an investigation into a phenomenon that happened on the wall surface of a Steam / Water Separator (SWS). It was reported that erosion caused from unknown solid particle took place on the SWS wall. In order to capture this sand erosion phenomenon numerically, the SWS flow field was solved, and then particle trajectory and wear quantity were calculated, based on the CFD results. Several wall and particle materials and also the combinations of them are assumed. Furthermore, the particle diameter was varied from 10−6 to 10−2 m. The numerical results insist that the particle, which could be the factor of the phenomenon, is limited in its diameter range and its material. The present study will be an aid to clarify the cause of sand erosion in a SWS.
