후류역 효율성 증대를 위한 해중림초 배치 모델

Abstract

This study presents placement models for marine forest artificial reefs (MFARs) to increase their wake region efficiency. For the purpose, first, ten line placement models are considered to investigate the effect of height difference between neighboring reefs on wake volumes. Second, seven single type placement models and eight mixed placement models are constructed. Third, wake volume of each placement model is calculated using the so-called element-based finite volume method. Finally, efficiency and unit propagation indices are estimated using the corresponding wake volumes and geometric characteristics of ARs. From the analysis results, it is shown a strong positive linear correlation between the efficiency indices and the height differences of the neighboring ARs. In addition, it is found that the mixed placement model with R1s (half-ball type reefs) improved both indices in comparison with the results of the single type placement models. Thus, a mixed placement model can be an alternative to improve the efficiency of wake region.
