摘要

In this paper,we investigate the microfluid induced vibration of a nanotube in thermal environment.Attention is focused on a special case that the law of energy equipartition is unreliable unless the quantum effect is taken into account.A nonlocal Euler-Bernoulli beam model is used to model the transverse vibration of a single-walled nanotube (SWCNT).Results reveal that the root of mean squared (RMS) amplitude of thermal vibration of the fluid-conveying SWCNT predicted from the quantum theory is lower than that predicted from the law of energy equipartition.The quantum effect on the thermal vibration of the fluid-conveying SWCNT is more significant for the cases of higher-order modes,lower flow velocity,lower temperature,and lower fluid density.
