Abstract
Recently, in various areas, equipments to separate and classify nano-size particles are required. We have investigating a new solid-liquid separator in order to efficiently separate nano-particles from liquid. This separator enables us to separate and classify nano-size particles by using centrifugal force and differences in specific gravity. A rotating screw in the separator is deformed by centrifugal force and flow drag, and thus the screw deformation may change the separation performance. Therefore, it is required to consider the screw deformation for the optimum design. In the present study, we computed the fluid-structure interaction between the screw and liquid with MPS method. It is confirmed that the flow field in the separator is changed by the screw deformation.
