摘　　要：运用三维不可压缩紊流模型,以截面为NACA4415翼型的机翼作送风口导流板,对室内流场进行数值模拟分析。本文分析了导流板与水平线夹角呈-30°的绕流流场及导流片截面弦长为3 cm时,室内流场分布情况。从模拟结果中可以分析目标区域舒适风速占比,房间大回流的位置以及诱导涡街的运动轨迹,对送风口在室内通风、空调送风的研究具有实际参考意义。A three-dimensional incompressible turbulence model is used to simulate and analyze the indoor flow field with the wing of naca4415 airfoil as the guide plate of air supply outlet.In this paper,the flow field around the deflector with an angle of-30°between the guide plate and the horizontal line and the distribution of the indoor flow field when the chord length of the guide vane section is 3 cm is analyzed.From the simulation results,we can analyze the proportion of the comfortable wind speed in the target area,the location of the large return flow in the room and the motion track of the induced vortex street,which has practical reference significance for the research of the air supply outlet in the indoor ventilation and air conditioning.
