Numerical Investigation of Fluid Flow Characteristics Around Slide Gates Using Multi-Zonal Method

One method of solving the governing equations of fluid flow about complex geometries is to use multi-zonal method. In this method the overall domain is divided into small number of simpler domains. In each zone, the flow field is solved independently of other zones. The boundary conditions for connecting zones are enforced to convey the necessary linkage. This multi – zonal procedure has been a...

Viscous Fluid Flow-Induced Nonlocal Nonlinear Vibration of Embedded DWBNNTs

In this article, electro-thermo nonlocal nonlinear vibration and instability of viscous-fluid-conveying double–walled boron nitride nanotubes (DWBNNTs) embedded on Pasternak foundation are investigated. The DWBNNT is simulated as a Timoshenko beam (TB) which includes rotary inertia and transverse shear deformation in the formulation. Considering electro-mechanical coupling, the nonlinear govern...
