摘要
建立了计算密度锁内流体分层界面位置的理论模型,比较了计算值与实验观察值,并分析了两者的区别,最后讨论了扰动速度和温差对界面位置的影响。结果表明:扰动速度增加,界面位置降低;温差变大,界面位置升高。在一定的温度和管径等条件下,分别拟合出界面位置与扰动速度及理查森数(Ri)的经验关系式。
A theoretical model is built to calculate the location of fluid stratified interface in density lock,the calculated values and experimental observations are compared and the difference between them are analyzed.The effect of disturbance velocity and temperature difference on the interface location is discussed,respectively.The result shows that the larger disturbance velocity responds to the lower interface location,and the higher temperature difference responds to the higher interface location.In condition of certain temperature and diameter,the experiential relationships among the interface location,disturbance velocity and Richardson number are fitted,respectively.
