| Summary: | 碩士 === 國立臺灣海洋大學 === 機械與機電工程學系 === 94 === The environmental consciousness ran high day by day during these years, any may cause the incident of the environmental pollution will be concerned specially. The ones that cause with the marine pollution among them are the most influential; the oil wastewater discharged must be regulated. In order to comply with this purpose, we can set up the oil-water separator on the shipping boat to reduce the ocean pollute. This study utilizes the FLUENT software to simulate the flow field within the hydro-cyclone. We expect that using this evaluation, we can obtain the separation efficient for subsequent reference for the design of flow fields. In this study, the Reynolds Stress Model (RSM) has been applied in the numerical method to predict the velocity fields of flow motion on the two different type hydro-cyclones.
We also use Discrete Phase Models (DPM) to calculate the separation efficient on those different type hydro-cyclones. The numerical results show that the device with conical part will have better performance than which without having it. The multi-phase fluid is much easier to be separated when the inlet flow is more close to the axis of hydro-cyclone.
