For the design guide of a vessel operating in cold region, numerical analysis was carried out to evaluate the ice class louver which installed the heating cables by using ANSYS 13.0 CFX. The numerical analysis was performed by considering Unsteady Reynolds Averaged Navier Stokes (RANS) equation. This study based on the experimental results of ‘The Cryogenic Performance Evaluation for the Excellent De-icing Ice Class Louver’ in KRISO. For validation of the numerical analysis results, the cold chamber experimental data measured by the heat sensors in certain location of the ice class louver was used. The external environmental temperature which varies from 0℃ to –30℃ was considered in numerical analysis. Also the design guide for optimum de-icing presented through heating cable power capacity(33 W/m, 45 W/m, 66 W/m), location of the heating cable(front, center, behind on the blade) and relative velocity(1 m/s, 4 m/s, 7 m/s).

극해 지역은 채굴가능 매장량의 30% 정도의 각종 천연자원이 매장되어 있으며 기후변화로 인해 북극해 항로를 이용한 운항 및 자원의 수송과 저장을 위해 빙해 선박과 극지용 해양구조물의 수요가 증가하고 있다. 이 연구에서는 아이스 클라스 등 방한기술에 근거하여 빙해 선박에 탑재되는 루버의 기술개발 동향에 대해 고찰 하였다.
