摘　　要：为降低汽车运输船(Pure Car Truck Carrier,PCTC)的噪声,减小其电力消耗,对风机房和风道的主要组成部分、独立风机房和结构风机房的不同的特点进行分析,并对货舱内部流场、通风阻力、噪声控制等3方面的关键技术进行研究。结果表明:货舱内部流场主要取决于通风总体方案;控制风道通风阻力是设计的关键,对风机房选型和控制噪声有很大影响;计算流体力学(Computational Fluid Dynamics,CFD)分析可有效提高设计的准确性。研究成果可为PCTC货舱通风设计提供一定参考。In order to reduce the noise and power consumption of Pure Car Truck Carrier(PCTC),the main components of the fan room and air duct,as well as the different characteristics of independent and structural fan rooms,are analyzed.Key technologies in the internal flow field,ventilation resistance,and noise control of the cargo hold are studied.The results indicate that the internal flow field of the cargo hold mainly depends on the overall ventilation scheme;Controlling the ventilation resistance of air ducts is the key to design,which has a significant impact on the selection of fan rooms and noise control;Computational Fluid Dynamics(CFD)analysis can effectively improve the accuracy of design.The research results can provide some references for the ventilation design of cargo holds on PCTCs.
