Abstract

The objective of this study is to present a resistance performance map developed using the dimension parameters of a bilge keel appendage attached to a fishing vessel using CFD. The dimension parameters consist of three length and breadth measures of a bilge keel appendage from nine selected cases. The size of a bilge keel attached to an existing ship should be 90 % of the ship length and 5 % of the ship breadth. In this study, bilge keels with a length of 63 %, 77 % and 90 % and a breadth of 5 %, 7 % and 9 % were considered based on ship length and breadth. The effective power in each of the nine cases was predicted using CFD. Based on results from an existing ship, effective power in the case with the shortest length and longest breath was reduced by 0.3 %. The case with the longest length and breadth showed an increase in effective power of 1.7 %. The case with the shortest length and breadth showed a decrease in effective power of 2.3 %. The proposed map can be utilized to select dimensions according to the sailing and work patterns of fishing vessels from the perspective of resistance performance.

본 논문의 주 목적은 전산유체역학(CFD)을 바탕으로 어선에 부착된 빌지킬의 치수 파라미터에 대한 저항성능 맵(MAP)을 작성하는 것이다. 치수 파라미터 스터디에는 빌지킬의 길이 3가지와 폭 3가지를 선정하여 9가지로 구성하였다. 현존선에 부착된 빌지킬의 길이는 배 길이 대비 약 90 %이고, 폭은 배 폭 대비 약 5 %이다. 수행항목은 빌지킬 길이는 배 길이 대비 63 %, 77 %, 90 % 그리고 빌지킬 폭은 5 %, 7 %, 9 %로 구성하였다. CFD 를 이용하여 9가지 빌지킬에 대하여 실선의 유효마력을 추정하였다. 현존선을 기준으로 길이가 제일 짧고 폭이 제일 긴 빌지킬의 경우 0.3 % 감소된 결과를 보여주었다. 길이와 폭 모두가 가장 긴 빌지킬의 경우 1.7 % 증가된 결과를 보여주었다. 길이와 폭 모두가 가장 짧은 빌지킬의 경우 2.3 % 감소된 결과를 보여주었다. 이 맵은 저항성능 관점에서 해당 어선의 이동 및 조업 패턴에 따른 최적의 부가물 치수 선정에 활용 가능하다.
