摘　　要：在建筑物火灾中,烟气运动对于火灾的蔓延、报警等有着重要作用。我们对有侧壁影响的受限空间中的烟气羽流进行了实验研究,测量了温度分布、速度分布和湍流脉动强度分布。结果表明,由于受到侧壁的影响,这些分布都呈现非对称性,羽流向粼近的壁面偏斜。It is important in the house fire to study the smoke mention in a confined region. We have studied experimentally a near-wall bouyant (smoke) plume in a confined region, the temperature, velocity and trubulent fluctuation velocity distribution were measured. The results show that the near-wall boryant plume in a confined region was unsymmetrical and may be a complex structure.
