... is especially relevant to creating arrays of semiconducting carbon nanotubes (CNTs) for high-performance electronics. When a dense solvent containing CNTs flows over a less dense water subphase in a confined channel, the locally aligned arrays of nanoparticles align globally with the flow direction and can...

... different inflow operating modes, independently; i.e., shutter valve opened ( λ ) 100% and 70%, respectively. The shutter valve opened completely at 100% represents flow in the straight channel without any backwater effects. The valve opened up at 70% represents a more complex condition in which...

Vortices Channel Pipe flows Corrugated pipes are widely used in offshore gas and oil fields as they offer global flexibility while maintaining local rigidity owing to the stiffening effect provided by the pipe corrugations. However, the associated free shear layer flow over the corrugations can...
