Abstract
This work presents an experimental study of the response of a liquid bridge formed between a sphere and a plane solid surface subjected to a vertical sinusoidal vibration. The amplitude and frequency of the oscillations can be varied. The successive movement of the particle along with the bridge deformation is registered to follow the dynamics of the system. The motivation is to figure out how capillary and viscosity forces can be modeled with the help of the experimental data obtained and to settle down a simplified theoretical approach capable of being implemented in the description of many phenomena involving wet granular grains. The results indicate that the viscosity effects can be neglected as soon as the amplitude of the movement is not too small, still obtaining a reasonable description of the dynamical behavior of the sphere/liquid-bridge system.
期刊介绍：
Although many phenomena observed in granular materials are still not yet fully understood, important contributions have been made to further our understanding using modern tools from statistical mechanics, micro-mechanics, and computational science.
These modern tools apply to disordered systems, phase transitions, instabilities or intermittent behavior and the performance of discrete particle simulations.
>> Until now, however, many of these results were only to be found scattered throughout the literature. Physicists are often unaware of the theories and results published by engineers or other fields - and vice versa.
The journal Granular Matter thus serves as an interdisciplinary platform of communication among researchers of various disciplines who are involved in the basic research on granular media. It helps to establish a common language and gather articles under one single roof that up to now have been spread over many journals in a variety of fields. Notwithstanding, highly applied or technical work is beyond the scope of this journal.
