中文摘要：
采用雷诺平均的Navier-Stokes方程与RNG的κ-ε涡粘性湍流模型，模拟了内设障碍物的冬季房间模型常用的3种不同通风方案下室内空气的速度场，温度场以及污染物的浓度分布。通过分析认为同侧下送上回的通风方式可使室内较好地保持热量，因此可有效地节约能源。对侧下送上回通风可使工作区得到较高的空气品质，较高的热舒适性和较高的通风效率。
英文摘要：
The Reynold averaged Navier-Stokes equations and the RNG κ-ε turbulence model are used to simulate the velocity field, temperature field as well as the concentration distribution of pollution under three kinds of ventilation patterns in room where barriers are laid out. Three common ventilation patterns of room models in winter are discussed. By studying the numerical results, the conclusions that the lower-side inlet and upper-side outlet on the same wall pattern can keep thermal in a better way so that it can save energy effectively, was gotten. The ventilation whose supply openings and return outlets on the opposite wall can make work area to achieve the best indoor air quality, thermal comfort and better ventilation efficiency.
