碰撞射流通风用于航站楼的舒适性研究
Study on thermal comfort of impinging jet ventilation system applied to airport terminal buildings
摘要：
以某航站楼为案例，借助Fluent软件模拟研究了碰撞射流通风的效果，分析了送风速度和喷口安装高度对竖直方向温度场、PMV及PD等的影响，得到了最佳的喷口安装高度和送风速度。计算结果表明，喷口安装高度为0.3 m、送风速度为1.6 m/s时空调舒适性最佳。

Abstract：
Taking an airport terminal building as an example, studies the effect of impinging jet ventilation with Fluent. Analyses the influences of air supply velocity and nozzle setting height on the indoor temperature field in the vertical direction, PMV and PD. Obtains the optimal air supply velocity and nozzle setting height. Calculation results show that the best nozzle setting height is 0.3 m and the best air supply velocity is 1.6 m/s.
