Abstract

This paper presents on a new damping element called the colloidal damper which is used a principle of surface extension force in nano pore of silica gel. Behavior of water in the pore is investigated using the molecular dynamics. Dissipation energy of the colloidal damper is concerned with the contact angles of water in the pore. So the contact angles are calculated for changing parameters, i.e. size of the pore, length of the hydrophobic material, velocity (pressure) of water flows into the pore. Then these results are compared with the experimental ones.
