WAKE TURBULENCE AND DIMENSIONAL LENGTH CHANGES INFLUENCE ON CONVENTIONAL SHIP BASED ON RESISTANCE CRITERIA

Abstract

In the utilization as a floating vessel, ships shall always interact with the dynamic of the fluids in her surrounding environment. Through this interaction, some wake turbulence will be formed as the ship cruise along the water. On a conventional ship, length has become one of the factors which can create various numbers and forms of wake turbulence, this wake turbulence then believed can provides the positive Turbulence Kinetic Energy (TKE) that be able to enhance the ship acceleration or the negative one which creates more ship resistance. The investigation concerned on how the dimensional length changes of the conventional ship will affect the TKE through the wake turbulence analysis. The research carried out numerically with Ansys Fluent CFD code for the further turbulence impact analyzing and will only focus on ship performance based on the resistance criteria with ideal condition boundary layer which can be the research parameter. The overall results were compared with published data for validation purposes. The results are also believed to be useful for the development of the maritime industry
