摘要
为了降低呼吸道等相关疾病在船舶住舱内传播感染的风险,以圆盘布风器、壁面贴附、舱顶贴附3种送风形式为例对船舶住舱内咳嗽液滴的传播特性以及排除效果进行模拟研究。结果表明,壁面贴附送风对咳嗽液滴的扩散有一定的抑制作用,且在该送风形式下咳嗽住员在中层床位时室内咳嗽液滴的排除效果较为理想。
In order to reduce the risk of spread infection for respiratory disease in the cabin,the spread characteristics and the discharge effects of cough droplets in the cabin are simulated by using three kinds of air supply forms,including disc distributor,wall attachment and roof attachment.The results show that air supply form of wall attachment can inhibit the diffusion of cough droplets to some extent,and this air supply form has better discharge effect on cough droplets from the residents in middle beds.
