| 摘 要： | 不同于以往孤立研究船舶进气装置的研究方法,本文采用三维数值模拟方法结合标准κ-ε模型对侧向进气装置内外流场进行了一体化数值研究。获得了侧向进气装置行驶过程中的气动参数分布以及进气室内部气流分布形态,得出气动损失最大位置,并通过定义总压恢复系数计算了船舶在行驶过程中的阻力分布。

| Abstract: | Different from the past isolated research approach on the shipping air intake device, three-dimensional numerical simulation method and normal model were used to research on the integration of inner and outer flow field of the lateral air intake device.Aerodynamic parameters distribution of it and flow field structures in the air intake device were obtained during the process of sailing.The results also show the location for the aerodynamic loss and the drag distribution of the ship by the definition of tot... |
