FEASIBILITY STUDY ON EFFECT OF STRUCTURAL FLEXIBILITY OF ASYMMETRIC PRE-SWIRL STATOR ON PROPULSION PERFORMANCE FOR KRISO CONTAINER SHIP (KCS)

The use of energy-saving devices is the most effective method for decreasing CO2 emissions, which an increasingly concerning environmental issue. asymmetric pre-swirl stator has been developed as device and successfully applied to various types vessels. In present study, a flexible material was determine variation in flow around its efficiency. A fluid–structure interaction (FSI) analysis system using Star-CCM+ (fluid) Abaqus (structure). proposed validated by comparing experimental results plate flowing fluid. 3,600 TEU KRISO Container Ship improvement performance compared previous optimum value achieved with rigid stator. Although this application conducted on model scale deformation small, indicated possibility not only increasing efficiency but also vortex risk blade.
