摘　　要：以某型满足ABSIRCC-SP符号冷藏集装箱船的货舱通风系统为研究对象,采用计算流体动力学CFD方法对通风系统的风机前端进风段和风机后端风管段分别进行数值模拟和流场分析。根据计算结果优化进风段的设计以降低进风阻力,并调整风管结构以满足IRCC-SP符号的风量要求。基于CFD方法设计的货舱通风系统顺利通过了IRCC-SP模型试验,模拟结果与试验数据吻合良好。研究表明,运用CFD方法进行通风系统分析,可以清晰地了解流场分布、通风阻力和风量分配等信息,以此评估通风方案的优劣,并指导优化设计。Taking the cargo hold ventilation system of a certain type of refrigerated container ship meeting the IRCC-SP symbol of ABS classification society as the research object, the computational fluid dynamics(CFD) method is applied to conduct numerical simulation and flow field analysis on the front inlet section and rear end duct section of the ventilation system respectively. According to the calculation results, the design of the air inlet section is optimized to reduce the air inlet resistance, and the air duct structure is adjusted to meet the air volume requirements of IRCC-SP symbol. The cargo hold ventilation system based on CFD method has passed the IRCC-SP model test successfully, and the simulation results are in good agreement with the test data. The results show that the flow field distribution, ventilation resistance and air volume distribution can be clearly understood by using CFD method to analyze the ventilation system, so as to evaluate the advantages and disadvantages of the ventilation scheme and guide the optimization design.
