Determination of Surface Tension and Viscosity of Liquids by the Aid of the Capillary Rise Procedure Using Artificial Neural Network (ANN)
The present investigation entails a procedure by which the surface tension and viscosity of liquids could be redicted.To this end, capillary experiments were performed for porous media by utilizing fifteen different liquids and powders. The time of capillary rise to a certain known height of each liquid in a particular powder was recorded. Two artificial neural networks (ANNs) were...
متن کاملSurface tension and contact angle measurements of a hexadecyl imidazolium surfactant adsorbed on a clay surface
The surface tension of 1,2-dimethyl-3-N-hexadecyl imidazolium tetrafluoroborate (Im BF4) as a function of concentration has been measured. Between 10−5 and 4× 10−4 mol/L, the surface tension decreases with increasing imidazolium concentration. Aggregate formation appears to occur at a concentration near 4× 10−4 mol/L for temperatures between 50 and 75 ◦C. Small angle neutron scattering measurem...
متن کاملAnalysis of Contact Angle in Capillary Invasion
The correct knowledge of the physical processes that control the fluid-fluid interface displacement at the pore-level is of increasing interest due to the growing possibility of direct simulation of immiscible displacement offered by the strong development of computers’ performance and numeric methods and to the increasing accuracy in three-dimensional reconstruction methods. Flow of immiscible...

متن کاملExperimental investigation of dynamic contact angle and capillary rise in tubes with circular and noncircular cross sections.
An extensive experimental study of the kinetics of capillary rise in borosilicate glass tubes of different sizes and cross-sectional shapes using various fluid systems and tube tilt angles is presented. The investigation is focused on the direct measurement of dynamic contact angle and its variation with the velocity of the moving meniscus (or capillary number) in capillary rise experiments. We...
