本文应用流体力学理论,对船体的泥水膜与船底形状尺寸之间的关系进行了理论分析。分析表明,阻止船底泥水侧泄,保持较多泥水将提高船底泥水膜的承载能力,从而使船体的滑行阻力减小。 据此进行了模型船体加装挡板的防侧泄滑行试验,试验得出20mm宽挡板的最佳高度为6 mm,用此挡板在原型船体最大功率档速度下运动,可使船体滑行阻力下降44％。
In this paper, the theory of fluid mechanics is applied to the theoretical analysis of the relationship between the size of the muddy water film and the shape of the bottom of the hull. The analysis shows that blocking the side discharge of muddy water from the bottom of the ship and keeping more muddy water will increase the carrying capacity of the muddy water film on the bottom of the ship, so that the sliding resistance of the ship body will be reduced. Based on this, the model side-mounted skid-proofing test of the model hull was carried out. The optimum height of the 20mm wide baffle was found to be 6 mm. Using this baffle, the baffle was allowed to glide at the maximum power of the prototype hull speed Resistance decreased by 44%.
