摘　　要：中间渠道作为特殊限制性航道,船舶航行阻力是其尺度确定的关键参数。针对现有船舶航行阻力计算方法,分析其适用性,选取考虑了航道宽度和吃水比等因素的俞中奇公式作为中间渠道船舶阻力的参考计算公式,设计中间渠道船舶航行阻力试验方案,并开展3000吨级散货船模航行试验,根据试验结果对俞中奇公式进行修正,利用Flow3D模拟船舶在不同断面系数下中间渠道中航行并提取阻力,验证修正公式的准确性。结果表明,修正后的经验公式计算结果与数模对比,最大误差不超过16.89%。该公式具有较高的计算精度,对中间渠道设计具有重要的参考价值。The intermediate channel is a special restricted channel,and the ship navigation resistance is the key parameter to determine its scale.This paper analyzes the applicability of the existing calculation methods for ship navigation resistance and selects YU Zhongqi s formula considering factors such as the channel width and draft ratio as the reference formula for the calculation of ship resistance in the intermediate channel.The paper designs the test plan of the ship navigation resistance in the intermediate channel and carries out the navigation test on a 3000-ton bulk carrier model.According to the test results,the paper revises YU Zhongqi s formula and uses Flow3D to simulate the ship navigation in the intermediate channel under different section coefficients and extract the resistance to verify the accuracy of the corrected formula.The calculation results of the revised empirical formula are compared with those of the numerical model and the physical model separately,and the maximum error is no more than 16.89%.The results show that the formula has high calculation accuracy and has an important reference value for the design of intermediate channels.
