Abstract
A separation device using swirling flow has been investigated and made practicable. In the present study, our subject is to develop a separation system of multiphase flow with solid and liquid. Especially, the technique for the separation and collecting the particle such as the cutting dwarf and oil in the processing waste fluid is one of important problems. Micro-bubbles, on the other hand, are used for the environmental improvement and washing. Micro-bubbles are used for elimination of oil and the solid particulates from waste fluid by the centrifuge in the present study. The behavior of solid particles and micro-bubbles in the swirling flow are observed as the first step of development in a solid-liquid separation system.
