摘要

为研究人工造雪机内混式单孔核子器的临界成雪高度，实验测量了在不同气水压力比及环境温度下的临界成雪高度阈值，分析了气水压力比及环境温度对临界成雪高度阈值的影响。结果表明：在气水压力比为0.40 MPa∶0.40 MPa的工况下，当环境温度为-5 ℃和-10 ℃时，临界成雪高度阈值不存在，但环境温度为-15 ℃时，可以实现成雪，临界成雪高度阈值为50~55 cm。当气水压力比为0.50 MPa∶0.45 MPa和0.50 MPa∶0.40 MPa时，-5、-10、-15 ℃环境温度条件下均能成雪，且气水压力比及环境温度对临界成雪高度具有一定的影响。在相同环境温度下，气水压力比越大，临界成雪高度越小；在保持气水压力比不变的情况下，随着环境温度从-5 ℃降至-15 ℃，临界成雪高度则随之减小，且在-10~-5 ℃温度区间变化趋势较为显著。

Abstract

In this study

the critical snow formation height of a mixed single-aperture nucleator in an artificial snow machine was examined. The threshold values of critical snow formation height were experimentally measured at different air-water pressure ratios and ambient temperatures

and the effects of air-water pressure ratios and ambient temperatures on the threshold values of critical snow formation heights were analyzed. The results showed that the threshold value for the critical height of critical snow formation did not exist at temperatures of -5 ℃ and -10 ℃ under the working conditions with a gas-water pressure ratio of 0.40 MPa∶0.40 MPa

but snow formation could be realized at -15 ℃

and the threshold value for the critical height of critical snow formation was 50-55 cm. When the gas-water pressure ratio is 0.50 MPa∶0.45 MPa or 0.50 MPa∶0.40 MPa

snow can be formed at ambient temperatures of -5 ℃

-10 ℃

and -15 ℃. The gas-water pressure ratio and ambient temperatures have a certain influence on the height of critical snow formation. Under the same ambient temperature

the greater the gas-water pressure ratio

the lower the critical snow height. Provided that the gas-water pressure ratio remains constant

the critical snow height decreases when the ambient temperature lowers from -5 ℃ to -15 ℃

and the trend of the change is more obvious in the temperature interval from -5 ℃ to -10 ℃.
