摘　　要：为研究冬季时贴附射流和送风量对睡眠舱环境的影响,采用计算流体力学方法建立睡眠舱的物理模型,探讨入住人员睡眠状态下采用不同通风工况时,舱内的气流场、温度场和二氧化碳浓度场变化,并选取吹风感比率作为流场舒适度评价指标.结果表明竖直贴附射流在改善空气质量和吹风感方面效果均最佳。In order to study the influence of attached jets and air supply on the environment of small and micro sleep cabins in winter,the physical model of the sleep cabin is established by computationalfluid dynamics.The changes of airflow field,temperature field and carbon dioxide concentration field in the cabin was simulated under different ventilation conditions.Draft rate was selects as an evaluation index of flow field comfort.The results show that vertical adhesion jet has the best effect in improving air quality anddraft rate.
