A wireless tomography system has been developed to measure the real-time behavior of solid-liquid two phase flow in the centrifuge for controlling a rotational velocity and particle supply rate. The purpose of this study is development of real-time behavior of solid-liquid two phase flow measurement technique and image conductivity distribution in rotating body because a technique for measuring the behavior of solid-liquid two phase flow in the centrifuges has not existed yet. In this study, a device to measure wirelessly behavior of solid-liquid two phase flow in stationary body has developed as a preliminary to measure in rotating body. A centrifugation technology for industry process should be improved to obtain more effective separation, shorten process time and save energy. These requirements are achieved by optimizing rotational velocity and particle supply rate. The realtime measurement of behavior of solid-liquid two phase flow for controlling the rotational velocity and the particle supply rate is essential. In other words, the real-time behavior of solid-liquid two phase flow measurement and the rotational velocity control become innovative technologies. Typical behavior of solid-liquid two phase measurement technics with easy handling in particles liquid two-phase flow uses process tomography because the process tomography is suitable for real-time measurement in a rotating body. Process tomography has high temporal resolution. This detector was used with the wireless because electrical cables are not available for centrifuges under high speed rotational condition. This wireless tomography system was used for a lab scale rotating machinery measurement experiment. Consequently, we could wirelessly measure the behavior of solid-liquid two phase flow in stationary body in real time and get data to image the behavior of solid-liquid two phase flow. This result images the behavior of solid-liquid two phase flow. Observing it enable to control a rotational velocity and particle supply rate. So this wireless tomography system can separate solid-liquid two phase flow efficiently.
