Thermal effect on terahertz wave propagations in nanotube conveying fluid.

An accurate model about the terahertz wave propagation in fluid-filled single-walled carbon nanotube, named non-local Euler-Bernoulli bean models, was studied in the past decade. The temperature is a key factor to study the mechanical properties of the nanostructures. This paper presents the thermal effect about single-walled carbon nanotubes. The governing equation for single-walled carbon nanotubes is developed through non-local Timoshenko beam theory, and size and surface effects are considered. The fluid flows quickly, and the terahertz wave propagation will be in the scope of the frequency. Thermal effect and liquid density significantly change the propagating frequency.
