为研究空调净化房间粒子运动与气流运动的关系，用已有的谱分解方法求解了湍流中描述粒子运动的基本方程——ＢＢＯ方程，得出了更接近实验结果的解析表达式。分析了房间气流中粒子运动与气流运动的关系，提出了根据气流速度的实测值计算气流中粒子运动速度的方法。对计算方法作了编程，并用房间气流速度的实测值计算了气流中的粒子速度。计算结果表明，在空调净化房间通过测量分析气流的运动规律来研究气流中微小粒子的扩散规律是可行的。
In order to study the relationship between particle motion and air flow in air-conditioned rooms, the BBO equation describing the motion of particles in turbulent flow is solved by the existing spectral decomposition method, and an analytical expression that is closer to the experimental results is obtained. The relationship between particle motion and air flow in the room air flow is analyzed, and a method for calculating the particle motion velocity in the air flow based on the measured value of the air flow velocity is proposed. The calculation method was programmed and the particle velocity in the air flow was calculated using the measured values of the room air velocity. The calculation results show that it is feasible to study the law of air flow in the air-conditioned room to study the law of the diffusion of tiny particles in the air flow.
