【摘要】 在考虑重力的基础上,为研究多孔介质内部液相为非饱和状态下的毛细升高特性,建立数学模型,得出毛细升高高度与时间的函数关系。以多孔陶瓷管为实验对象,验证模型正确性并分析毛细升高高度变化的影响因素。结果表明颗粒直径越小,最终毛细升高的高度越大;在液体可流动的范围内,饱和度越低,其毛细升高高度越高;多孔介质倾斜角的大小影响毛细升高的长度,但初期的长度相同。更多还原

【Abstract】 Considering the effect of gravity, to study characters of the capillary rising when the porous media’s internal liquid as unsaturated state, we will establish a mathematics model, and obtain rising height as a function of time. Then we choose porous ceramic material tube as the experimental object to validate the model and analyze the influence factors. The results show that when the working medium is water, the particle diameter is smaller, eventually the height of the capillary rise is larger; within the scope of the liquid flow can be critical, the degree of saturation is lower, the capillary rise height is higher; the size of the porous medium angle affect the length of the capillary rise, but in the early, the rise is in the same height.更多还原
