摘　　要：以分析风挡结雾过程的瞬态特性为目标,首先建立了风挡温度控制方程和定解条件,然后分析了座舱湿度的计算方法以及单个雾滴与其周围环境的换热特征,最后确定了风挡内表面附近湿空气的凝结速率。以上瞬态模型能够对飞机风挡结雾过程的数值模拟提供有效的理论依据。In order to study the transient characteristics of the fogging process,this paper accomplished the following investigations.Firstly,the temperature control equations were established,and so as its boundary conditions and initial conditions.Secondly,computation methods about the humidity of cabin air was specified.Meanwhile,the heat transfer performance between single fog droplet and internal air flow as well as windshield was also investigated.Finally,the condensation rate of cabin air around the inner surface of windshield was defined.The above-mentioned transient models can offer effective theoretical basis for numerical simulation about the fogging procedure on aircraft windshield.
