本文采用两相流混合模型，对居室厨房内颗粒的分布和运动进行了数值模拟。通过对厨房空气流场和颗粒物浓度的分析，发现厨房环境中颗粒物浓度的分布受温度和气流速度的影响。针对这两点，对不同直径、不同季节(夏季和冬季)的厨房内颗粒物的分布进行了详细的研究，得出的结论可以提高厨房内颗粒物的去除效率，对设计合理的通风方式具有一定的参考价值。
In this paper, the distribution and motion of the particles in a residential kitchen was simulated numerically using mixture model of two-phase flow. By analyzing the air flow field and the concentration of the particles, it was found that the distribution of particle concentration in kitchen environment was influenced by the temperature and the velocity of airflow. In view of these two points, the distribution particles of the different diameter and different season (summer and winter) in a kitchen was investigated detailed, the conclusions can improve particle removal efficiency in the kitchen, and are very useful to design reasonable ventilation method.
