다국어 초록 (Multilingual Abstract)

<P><B>Abstract</B></P> <P>In this study, a Computational Fluid Dynamics (CFD) to analyze the coastal waste particles in a wind-power sorting system is applied to produce renewable fuel using commercial CFD package (ANSYS-CFX code). The numerical methodology results predicted various coastal waste shredded inside the sorting machine. Furthermore, to identify the effect of working conditions on separation characteristics, a parametric study is performed. These study findings will offer appropriate a wind-power sorting conditions according to the purpose of using coastal waste. Under basic conditions, the characteristics of coastal waste particle behavior and the sorting of waste particles were analyzed, and the behavioral changes of diverse particles were identified by changing the airflow rate to improve the sorting performance. As a result, an appropriate airflow rate, Q<SUB>air</SUB> = 85 m<SUP>3</SUP>/min, at which the change in the airflow rate can simultaneously meet the conditions for both the recovery of the combustibles and the removal of the incombustibles, was selected with the selection efficiency rate was 92%, and the combustibles content was 99%. Based on the results of the analysis, the particle characteristics of sorting were identified to reduce and recycle the coastal waste.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Coastal waste has become a serious global problem in the marine environment. </LI> <LI> The producing solid fuel from the coastal waste is a representative example. </LI> <LI> To produce high-quality SRF, it is important to effectively sort out combustible. </LI> <LI> CFD result provided the prediction of behavior of waste particle in sorting machine. </LI> <LI> The particle characteristic of sorting identified to recycle the coastal waste. </LI> </UL> </P>
