정수 중 프로펠러의 상하 동요에 따른 성능 변화에 관한 수치적 연구

초록

As the introduction of EEDI regulations and the international environment is becoming more stringent, newly built ships are required to reduce carbon emissions than the present. Already in many marine fields, we are making a lot of efforts to reduce carbon emissions, and building vessels with low carbon and high efficiency has become a great competitiveness in the marine field. The heaving motion of propeller is one of the factors affecting the propeller performance. In waves, the interaction between the propeller and the free surface by the motion of the hull causes ventilation, which affects propeller performance. In this study, we implemented the heaving motion of propeller using the overset method by STAT CCM+. Moreover, we compared propeller performance during the heaving motion of the propeller at the same advance coefficient and propeller performance according to the immersion depth of the propeller in calm water.
