The average concentrations of CO and NO2 at the toll gates don't exceed the indoor and outdoor air quality standards except for the toll gate in Chongqing and Chayuan. One-hour average concentrations of outdoor and indoor THC are 7.728 mg/m3 and 7.216 mg/m3 respectively, and exceed ten times of the indoor air quality standard. One-hour average concentrations of indoor and outdoor PM10 change acutely respectively, and the their maximum concentrations are 0.631 mg/m3 and 0.217 mg/m3 which exceed indoor air quality standard and the second class of ambient air quality standard.

The thickness of the ice cover on the wall surface heat transfer is greater than the thickness of it on the air heat transfer form. The thickness of the ice cover on the wall surface heat transfer along the way changes slowly, but it on the air heat transfer along the way changes significantly. Reducing the entrance velocity, lowering the wall surface or air temperature, the formation of the thickness of the ice cover will increase; in the 3D circumstances, The thickness of the ice cover was relatively uniform in the import of the U-turn model, the ice cover was gradual accumulation in the convex bank when the stream traversed the import of the U-turn model, the thickness of the ice cover in the convex bank was significantly bigger than the thickness in the concave bank. The temperature field under the ice cover tends to be complex because of the existence of the secondary flows. The temperature in the convex bank is greater than it in the concave bank. Compared with the data from experiments, the laws in the numerical simulation are similar with them in the experiments
模拟结果显示:二维情况下,运用壁面传热形成的冰盖厚度大于运用空气传热形成的冰盖厚度,壁面传热形成的冰盖厚度沿程变化缓慢,而空气传热形成的冰盖厚度沿程变化明显,减小入口流速,降低壁面或空气温度等,形成冰盖的厚度都会增大;三维情况下,弯道入口处凸、凹岸形成的冰盖厚度基本相同,进入弯道后,凸岸形成的冰盖厚度逐渐增大,而凹岸的冰盖厚度逐渐减小,受横向环流的影响,冰盖下水流的温度场趋向复杂,并且凸岸的温度小于凹岸的温度;与实验室实验所得数据相比较,数值模拟研究得到的规律基本符合实验规律。

The solutions were found to be good agrees with experimental results. The transfer characteristic of air dry/wet bulb temperature and spraying water temperature were discussed. The LMTD method based on this mathematical model is applicable to design and verify for the plate wet air cooler. The ratio of the wet bulb heat transfer coefficient to the heat transfer coefficient under air-cooled conditions was investigated theoretically and experimentally. The relative errors of the ratio between theoretical and experimental valves are small than 7 percent.
