Spur dike is one of the hydraulic structures used in rivers to protect river banks. In this paper, flow pattern around a T-shaped spur dike which is located in a 90◦ bend and different amounts of submersion has been studied using Flow-3D. Numerical results have been compared with experimental results and have been analysed.

Turbidity currents in the ocean and lakes are driven by suspended sediment. The vertical profiles of velocity and excess density are shaped by interaction between the current and bed as well as between the current and the ambient water. This paper presents 48 series of experiments in which saline gravity currents flow through a laboratory sinuous flume. flume contains three successive bends wit...

We report a very low-loss hybrid silicon waveguide circuit consisting of straight rib sections with a propagation loss of 0.272±0.012 dB/cm and compact photonic wire bends of 5μm radius with a loss of 0.0273±0.0004 dB/90 o bend.

Simulated stormwater management devices baited with alfalfa infusion were constructed to test conveyance pipe dimension and orientation as a potential deterrent to mosquito oviposition. Various configurations of pipe diameter, length, and orientation were evaluated based on egg raft counts. Field trials tested pipes of 1.3-, 5-, and 10-cm diam and 0-, 90-, or 270-cm lengths, in both horizontal ...

The design and experimental demonstration of a large, ultrahigh-quality (Q) factor, single-mode operation silicon ring resonator based on strip photonic waveguide are presented. comprises multimode straight waveguides (MMWG), (SMWG), 90° Bezier bends, linear tapers. SMWG used in the coupling region to achieve mode for fundamental without exciting higher-order mode. MMWG, 1.6 μm width, decrease ...
