摘　　要：目的研究与分析在开启厨房排油烟机满足其排污要求风量条件下的室内气流分布状况,给出合理地补风口尺寸.方法运用CFD-fluent软件,采用计算流体动力学数值模拟的方法,以常见民用住宅中50 m2的户型为研究对象,模拟以卧室窗户下方长、宽为1.8 m×0.05 m的缝隙作为进风口,厨房排油烟机作为出风口工况下的室内气流组织.结果得到该工况下室内气流速度分布图,压力分布图,速度矢量图,剖面图等等.结论主要影响排风效率的是补风口的位置与大小,当补风口设在窗下,截面尺寸为1.8 m×0.05 m,排风量为324 m3/h时能形成合理地气流组织,满足排风要求,有效地排出污浊气体.Investigating and analyzing the indoor air distribution under the condition of opening kitchen exhaust fan to satisfy wind quantity, so as to get reasonable air-makeup orifice size. Using CFD-fluent software and adopting numerical imitated hydrodynamics calculation method, with family residential building of 50 m^2 type for research object, this paper simulates indoor air distribution that with 1.8 m×0. 05 m gap under the window for receive wind stomata and with kitchen exhaust fan for vent stomata. Finally, this paper will get velocity distributing plot, pressure distributing plot, velocity vector plot, section plane. The main influence factor of exhaust efficiency is the position and size of the air-makeup stomata. When it is under the window with 1.8 m×0. 05 m size, 324 m^3/h wind quantity can form reasonable air organization and validly eject dirty air.
