    Abstract: This paper presents an analytical solution to a coupled vibration problem of fluid-conveying
    double-walled carbon nanotubes (DWCNTs) and analyzes the influences of nonlocal effect,
    aspect ratio and van der Waals interaction on the fundamental frequency. According to the
    analysis, the results show that the vibration frequencies of the first three modes of DWCNTs are
    lower than those of single-walled carbon nanotubes (SWCNTs). The trend is more obvious
    when the flow velocity is high. It can also be found that the velocity of vibration-induced flutter
    instability for DWCNTs is lower than that of SWCNTs. In addition, the frequency of mode 1 of
    DWCNTs decreases with increasing nonlocal parameter. However, the frequency increases as
    the aspect ratio and the van der Waals interaction increased, especially at higher flow velocities.
