摘　　要：利用CFD模拟研究分析了室内应用碰撞射流送风方式时,不同的送风口特征对碰撞射流近地面气流形态的影响。结果表明:研究碰撞射流通风吹风感时,仅研究0.1m高度的气流速度是不够的,需要选择0.1m高度以下的垂直方向气流速度最大值作为评判标准。CFD simulation is used to analyze the influence of different characteristics of air supply outlet on the air flow pattern of impinging jet near the ground.The results show that it is not enough to study the air velocity at the height of 0.1 M when studying draft sensation of impinging jet ventilation,and the maximum value of the air velocity in the vertical direction below the height of 0.1 M should be selected as the evaluation standard.

关 键 词：碰撞射流通风 速度场 吹风感 数值模拟
