摘要:
人体运动对室内气流分布有直接而重要的影响. 采用CFD方法对一种新型通风方式—竖壁贴附射流通风房间内人体运动进行了数值模拟分析与评价. 采用动网格技术实现人体运动,并将人体运动简化成长方体平移运动的形式. 采用动态分层法更新体网格,研究了人体不同运动速度对室内速度场的影响,并对室内气流分布性能进行评价. 发现人体运动速度越大,其横向影响范围就越大,而纵向影响范围一般在2 m以下. 另外,研究表明,人体运动会影响室内人员的热舒适,但短期运动的影响持续时间较短. 关键词: 中图分类号:文献标志码:A文章编号:
Abstract:
Human movement has a direct and important influence on indoor air distribution. The CFD modeling is adopted to analyze and evaluate the characteristics of the human body movement under the condition of air curtain ventilation, a new ventilation way. Human movement can be simplified into a cuboid translational motion realized by dynamic grid technique with the dynamic layering method updating grid. The paper studied variation of the indoor velocity field and evaluated indoor air distribution at different human movement speed. It shows that the greater human moving speed is, the larger horizontal sphere of influence becomes, whereas there is little influence on vertical sphere over 2 m. Additionally, human body-motion has an adverse effect on thermal comfort, and the influence of short-term movement has short duration.
