摘要
针对船舶压载水系统对紫外(UV)杀菌器腔体设计技术水平要求高的特点,应用计算流体动力学(CFD)方法对UV杀菌器中压载水的杀菌过程建立数值模拟模型,并以300 m3/h处理量的UV杀菌器为对象,对其内部流场进行了模拟计算,重点对水力、辐射、剂量进行了模拟分析,获得了腔体内辐射剂量分布情况,并通过生物实验来检测实验装置是否满足IMO标准.
Ultraviolet light disinfection is an important kind of sewage depth processing method.By using compu-tational fluid dynamics （CFD）methods,the internal flow field in the uv tube is simulated and computaed,using Fluent software for hydraulic,radiation,dose of simulation analysis to obtain the distribution of radiation in the cylinder.And biological experiments were done to test whether it meet the standard of IMO.
