查询词典 air-raid

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

The simulation results show that staged air can significantly reduce tangential circle diameter of upper parts of furnace and lower heat transfer difference of horizontal gas flue; the field test results show that the proper ratio of staged air in the total air can make tubes wall temperature distribution of high-temperature superheater uniform, and tubes' peak temperature lowered 5~10℃.

模拟计算结果表明炉内分级送风对于减小炉膛上部切圆直径、降低水平烟道内的热偏差作用明显；现场试验结果表明，适度增大炉内分级送风比例使高温过热器管壁温度分布更均衡，峰值温度降低5～10℃，使受热面运行安全性得以提高。

During the siege of Dien Bien Phu, the Vietminh moved in heavy antiaircraft artillery formations and succeeded in inflicting air denial upon the French; by May 1954, just before the collapse, French fighters and bombers (let alone transports and liaison airplanes) could not operate over the valley without taking prohibitive losses.18 American fixed-wing aircraft losses in Southeast Asia, while not large in the context of the entire SEA air effort, were certainly not inconsequential, and the introduction of the shoulder-fired SAM during the 1972 North Vietnamese spring offensive added a new problem for tactical air planners.

The invention discloses an hot water production method complementary of air heat source and steam exhaust exhaust heat, is characterized by employing an air source heat pump to heat up tap water by temperature of 8-12 DEG C; recycling steam exhaust in washhouse to reheat up the hot water from the air source heat pump by temperature of 55-70 DEG C, and feeding the hot water into a hot water reservoir for standby.

本发明公开了一种空气热源与乏汽余热互补的热水制造方法，其特征在于，采用空气源热泵加热自来水，使自来水的温度升高8～12℃；再回收洗衣房内的乏汽将空气源热泵输出的热水进行二次加热，并将其升温至55～70℃，将所得热水送入热水蓄水池备用。

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.
