摘　　要：以吸烟室为研究对象,基于CFD模拟与步进电机实验相结合,对烟气在吸烟室中的扩散进行数值模拟,并通过PIV实验测量烟气速度进行模型验证,相对误差在25%以内。最终,得到了不同送排风方式、不同烟气源量、不同新风速度下的室内烟气速度和CO质量分数分布。结果表明:侧送上排是更加有效的净化室内烟气的送排风方式;吸烟室内不同高度的烟气浓度主要取决于送排风方式、污染源的位置;增大烟气源量,会使室内气流对流加强,气流流速加快,且室内烟气浓度较高,烟客受到二手烟的危害较高;增大新风速度是降低吸烟室内烟气浓度的有效方法。This thesis takes smoking room as research object.Based on the combination of CFD simulation and the stepping motor experiment,this paper carries out numerical simulation of the smoke diffusion in the smoking room.The model is verified by PIV experiment,and the relative error is less than 25%.In the end,the indoor smoke velocity and CO mass fraction distribution under different ventilation modes,different smoke source quantities,and different fresh air velocity were obtained.Results showed that the upper side exhaustion is a manner of purifying the indoor smoking effectively.The indoor smoke concentration in different heights is mainly decided by exhaust manners and pollution source location.To increase the smoke source quantity will enhance the indoor air convection,and accelerate the airflow speed with relatively high indoor smoke concentration.The smokers will suffer much more damage from the second hand smoking.To accelerate the speed of new ventilation system is an effective method to decrease the indoor smoking concentration.
