实验研究了湿空气在泡沫金属内流动析湿过程的传热传质特性，得出了不同因素的影响规律。研究结果表明，随着入口空气相对湿度、温度和速度的增加，总换热量增加，且空气温度的影响比较明显；当入口空气温度由25℃增大到35℃时，换热量最大可增加82%；随着冷却水温度升高，潜热和显热换热量均减小，且潜热换热量降低幅度更大。与同体积的开窗翅片管式换热器相比，析湿工况下泡沫金属换热器内的湿空气换热量提高40%~112%。1
The heat transfer characteristics of moist air in metal foam during flow and dehumidification processes were investigated experimentally, and the influence principles of different factors were obtained. The results show that, the total heat transfer rate increases with the increasing inlet air relative humidity, temperature and velocity, and the influence of air temperature is more noticeable than that of the other factors; as the air temperature increases from 25℃to 35℃, the total heat transfer increases by 82%;the latent and sensible heat transfer rates decrease with the increasing cooling water temperature, and the latent heat transfer has much greater deterioration. Compared to louvered fin and tube heat exchanger, metal foam heat exchanger with the same volume can enhance heat transfer capacity by 40%~112%under the dehumidifying conditions.

采用考虑自然雾对太阳辐射的衰减、散射作用进而修正的太阳辐射模型,且考虑含雾湿空气条件下雾滴、湿空气与目标表面的换热机理及表面辐射换热、对流换热,建立了含雾湿空气条件下地面目标热特征分析模型,采用该模型计算分析了雾能见度、风速对目标表面温度的影响,分析了典型雾天条件下目标表面温度变化特性。结果表明:在雾出现时段,雾能见度越小或风速越大,目标表面温度值相对越低;考虑雾对目标表面热特征的影响具有很大的必要性。
Based on the modified solar model by considering the attenuation and scattering of the fog, and considering the heat transfer mechanism between fog droplets and target surface in the foggy weather and the radiation and convection heat transfer of the surface, the heat transfer model of the ground target surface in the foggy weather was founded. The influence of fog visibility and wind speed on the target temperature field was analyzed by the heat transfer model. The temperature time variation characteristics of the targets in the typical foggy weather was also analyzed. The result shows that during the appearance of the fog, the smaller the fog visibility, the lower the temperature of the target surface; the higher the wind speed, the lower the temperature of the target surface. So it′s very necessary to consider the influence of the fog and wet air during the heat calculation of the ground targets.
