| 摘 要： | 用计算流体力学（CFD）数值方法以实际空调办公房间为研究对象，在4种不同工况下，对室内流场分布和人体的舒适性进行了模拟和分析。结果表明：在低风速和低湍流度的进风口气流下，人体由于新陈代谢在头部上方产生最大速度为O．2445m／s的上升气流；在4种工况下，人体对风速为1．35m／s，湍流度为32．6％的近似自然风感觉最好，为办公室人体舒适性研究提供了一定的依据。

| Abstract: | Based on the computational fluid dynamics （CFD） numerical method, the flow field distribution and thermal comfort around human body under four different wind speeds and turbulence intensity of boundary conditions were simulated and analyzed. The results showed that a thermal plume produced by the metabolism of human body, with a maximum velocity of 0.2445 m/s, may form above the head of the occupant,under the condition of low wind speed and low turbulence intenity of the inflow air. Among the four different wind speeds and turbulence intensity levels, the occupant feels most comfortable with awind speed ofl.35 m/s and a turbulence intensity of 32.6 %. |
