摘  要:
为了研究"上海市渔船标准化节能船型"中30 m级桁杆拖网渔船的阻力特性,将计算流体力学应用于标准化节能船型的数值模拟计算中,通过采用k-ωSST(剪切应力输运)湍流模型和求解不可压缩流体动量方程,来计算该船型的裸船体状态下的不同航速对应的阻力值。文中详细叙述了建模、设定条件、划分网格等作业流程,其计算结果与船模试验结果高度吻合,可为中小型渔船的节能降阻研究提供理论依据。

摘  要:
In this paper,we focus on the calculation of resistance of 30 m beam trawler in "Research on the Standardized Energy-saving Ship Form for Shanghai Fishing Vessel".We apply time-averaged Navier-Stokes equation(RANS) in conjunction with k-ω turbulence model to compute resistance of naked hull under different speeds.Details on ship model,boundary conditions and mesh generation are discussed.The computation results agree well with ship model test results.This paper provides a basic foundation for saving energy and reducing the resistance of small fishing vessel.
