Free vibration of the water-filled single-walled carbon nanotubes

摘要

A double shell-potential flow model is developed to study the free vibration of the water-filled single-walled carbon nanotubes (SWCNTs) in the paper. SWCNTs are coupled with inner water via the van der Waals (vdW) interaction. It is shown that the vdW forces upshift the frequency of the SWCNTs. The results also reveal that the internal moving fluid plays an important role in the instability of system whereas the fluid velocity has very little influence on the dynamic characteristics of the tube.
