in river meandering, when flow passes through a bend, reduction of flow velocity and rising hydrostatic pressure cause super elevation phenomena at outer side and reduction of water surface at inner-side of the bend. a helical motion results, causing erosion of the outer side of the bend. installation of submerged vanes on the stream bed can reduce erosion of the outer bank significantly. in th...
Recently, a new layout style to avoid edge crossings in straight-line drawings of non-planar graphs received attention. In a Partial Edge Drawing (PED), the middle part of each segment representing an edge is dropped and the two remaining parts, called stubs, are not crossed. To help the user inferring the position of the two end-vertices of each edge, additional properties like symmetry and ho...
A numerical study, using the volume-of-fluid method (VOF), has been made of core-annular flow in a curved pipe. We investigated two cases: core-annular flow in a 90◦ bend and in a 180◦ return bend. To verify our numerical method we first compared our results for a singlephase flow in a 90◦ bend with numerical results and experimental data given in the literature. The agreement was good. Thereaf...
In this work, a plasmonic right-angled waveguide bend and divider are proposed. Using the Transformation Optics (TO) approach transformation media of T-shaped obtained. Such with continuous refractive index realized help graphene in terahertz frequency range, key to effectively guiding surface plasmon polariton (SPP) propagation on 90 degree curves. Components such capability promising for THz ...

Flow in river bends is associated with generation of secondary flows that leads to a rather complicated flow pattern around bridge piers located the bend. In this study, patterns rectangular and oblong models collar at 90o angle 180-degree sharp bend an experimental plume were investigated. The 3D velocity data collected using Vectrino velocimeter. results indicated presence pier caused more in...
