摘要
通过实验研究了不同加热功率下的间歇泉流动现象,并对实验现象和实验数据进行了分析。给出了流动变化的平均周期和加热功率之间的计算关系式。结果表明:在间歇泉流动中,系统内的液体会周期性地沸腾,并循环出现多种流动形态;液体的冷却回流过程中会产生较大的温度和压力变化;随着功率的加大,间歇泉流动的变化周期变小,管路内的流动变化以及温度和压力波动越发剧烈。
Experimental study on liquid periodically boils at different heating power and analysis the experimental phenomenon and data.A correlation is given to describe the relationship between the period of geysering and heating power.The result shows that the liquid periodically boils and various flow patterns alternately occur.The refilling of cooler liquid causes significant change of temperature and pressure in the system.The period of geysering decreases with the increase of heating power.The flowing in the system varies more greatly as well as the pressure and temperature of liquid.Furthermore,a correlation is given to describe the relationship between the period of geysering and heating power.
