GAS BUBBLE DISPLACEMENT FROM CAPILLARY BY LIQUID

 

UDC 532.6: 622.7

Language: Russian

Abstract. Problem of impregnating a body with a homogeneous porous structure is considered in a simplified formulation. Since real process of the gas bubble displacement from a single capillary, which is immersed into liquid, cannot be modeled, the problem was analyzed theoretically. It is shown that, basically, the process under the study consists of two stages: compression of the bubble and its displacement from the capillary. In this case, the displacement duration was predominant. Basing on the assumption that pressure in the bubble was constant, an analytical expression was obtained that determines, within the domain of time, change of the height of the liquid level that displaces the gas bubble. Theoretical results were compared with obtained earlier experimental dependence of the basalt sample saturation with water, and the comparison showed satisfactory qualitative coincidence. In order to obtain more accurate theoretical description of the impregnation process, it is necessary to take into account structural characteristics of the samples to be impregnated.

Keywords: impregnation, gas bubble, liquid, meniscus, angle of wetting, capillary.
