摘　　要：为了准确预测大型船舶在浅水狭窄区域航行规律,应用CFD计算方法,基于STAR-CCM+软件,通过求解RANS方程,明确仿真要素,构建仿真模型,对航行船舶建立水动力模型进行数值模拟,得出不同航道宽度和水深下船舶阻力和下沉量随航速的变化情况,为验证数值模拟的准确性,将软件模拟计算结果与船模试验结果进行对比。研究结果表明,模拟船舶阻力与下沉量计算结果与船模试验数据吻合良好,误差控制在7%以内,在STAR-CCM+平台上模拟计算方法可以快速和准确地预测船舶水动力性能及航行规律,为后续通航隧道的设计提供理论支持和参考;保证STAR-CCM+模拟算例精确度的前提下,试验得出不同航速下不同航道水深和航道宽度对船舶航行的影响,提出船舶通过该水域安全航速范围。In order to accurately predict the navigation law of large ships in shallow water and narrow areas,CFD calculation method and STAR-CCM+software are applied to solve RANS equation,identify simulation elements,build simulation models,and establish hydrodynamic models for sailing ships for numerical simulation.The changes of ship resistance and subsidence with speed under different channel widths and water depths are obtained.In order to verify the accuracy of the numerical simulation,the software simulation calculation results were compared with the ship model test results,and the research results showed that:The calculation results of the simulated ship resistance and subsidence are in good agreement with the ship model test data,and the error is controlled within 7%.The simulation calculation method on the STAR-CCM+platform can quickly and accurately predict the ship's hydrodynamic performance and navigation law,and provide theoretical support and reference for the subsequent design of navigable tunnels.Under the premise of ensuring the accuracy of STAR-CCM+simulation examples,the influence of different channel water depth and channel width on ship navigation under different speed is obtained,and the safe speed range of ships passing through the water area is proposed.
