Resumen:
We present a simple model to describe the
response of a granular bed to a tapping-like excitation when
grains can form capillary bridges due to the presence of interstitial
liquid. We implement a pseudodynamic simulation of
adhesive hard disks. The packing fraction and coordination
number after the steady state of the tapping process has been
reached are compared for different tapping intensities and
liquid contents. We find some contrasting behavior with dry
systems and qualitative agreement with experimental data.
