摘　　要：该文从热力学、传热传质学、流体力学的基本原理出发 ,对饱和器内水滴侧和湿空气侧分别建立沿流动方向的一维动态数学模型 ;该模型在仿真平台EASY5上调试通过 ,通过计算得到饱和器稳态运行时的数据 ,然后完成了一组动态响应下的仿真实验 ;结论认为饱和器在稳态运行时 ,沿气体流动方向 ,气体质量流量增加 ,密度减小 ,速度增加 ;沿水滴流动方向 ,水滴的温度和速度降低 ,水滴浓度增加 ,水滴直径变小 ,但是水滴侧与空气侧的接触总面积却依然增加 ;对饱和器的动态响应而言 ,如果进水量出现扰动 。Based on the thermodynamics, mass transfer and heat transfer, hydromechanics, a dimensional dynamic mathematical model of the water droplet and humid air in the humidifier is erected. Then the model is debugged on the EASY5 platform. Through calculation, the steady data of the humidifier are gotten, then one dynamic response of the simulation experiment is finished. At steady state, along the gas path, the gas mass flow increases, the density decreases, and the velocity increases; along the water path, the water droplet temperature and the velocity decreases, the droplet density increases, the droplet diameter decreases, but the total contact area between the droplet and the gas still increases. To the dynamic response, if the inlet water mass flow is disturbed, the air can response it quickly.
