Terahertz Wave Propagation in a Nanotube Conveying Fluid Taking into Account Surface Effect

Terahertz Wave Propagation in a Nanotube Conveying Fluid Taking into Account Surface Effect

In nanoscale structure sizes, the surface-to-bulk energy ratio is high and the surface effects must be taken into account. Surface effect plays a key role in accurately predicting the vibration behavior of nanostructures. In this paper, the wave behaviors of a single-walled carbon nanotube (CNT) conveying fluid are studied. The nonlocal Timoshenko beam theory is used and the surface effect is t...

Rigidity and Irregularity Effect on Surface Wave Propagation in a Fluid Saturated Porous Layer

The propagation of surface waves in a fluid- saturated porous isotropic layer over a semi-infinite homogeneous elastic medium with an irregularity for free and rigid interfaces have been studied. The rectangular irregularity has been taken in the half-space. The dispersion equation for Love waves is derived by simple mathematical techniques followed by Fourier transformations.  It can be seen t...

Leaf Deformation Taking Into Account Fluid Flow

This paper proposes a method for animating leaf structural deformation considering the leaf water content and its change due to evaporation. To achieve this we embed a massspring system into a mesh representing the leaf, and couple the mass-spring parameters with a simulation representing the fluid flow and evaporation occurring in the leaf. This chain of events aims to simulate the natural pro...

Longitudinal Wave Propagation Analysis of Stationary and Axially Moving Carbon Nanotubes Conveying Fluid

In this study, the effect of small-scale of both nanostructure and nano-fluid flowing through it on the natural frequency and longitudinal wave propagation are investigated. Here, the stationary and axially moving single-walled carbon nanotube conveying fluid are studied. The boundary conditions for the stationary nanotube is considering clamped-clamped and pined-pined and for the axially movin...
