This paper numerically and experimentally investigates and demonstrates the design of an optofluidic in -plane bi-concave lens to perform both light focusing and diverging using the combined effect of pressure driven flow and electroosmosis. The concave lens is formed in a rectangular chamber with liquid core liquid cladding (L) configuration. Under constant flowrates, the performance of the le...

Using the Condon model to describe the dispersive behavior of optically active media, we analyze two different classes of waves in chiral optical fibers: surface and semileaky modes. Only when the cladding is chiral, semileaky modes do exist; accordingly, optical fibers with either chiral or achiral cores, but always with a chiral cladding, are considered. Two fundamental modes, corresponding t...

The cladding of a modern building is a critical, and expensive, specialist subsystem of the total building. This paper is concerned with modelling the supply chain processes within the building cladding sector of the UK construction industry. The modelling was conducted within the context of CIMclad, a research project involving a consortia of universities and industry that is seeking to move t...

In this Article dispersion characteristic of conventional optical waveguide with helical winding at core – cladding interface has been obtained. The model dispersion characteristics of optical waveguide with helical winding at core-cladding interface have been obtained for five different pitch angles. This paper includes dispersion characteristics of optical waveguide with helical winding, and ...

Abstract The interfacial microstructure and hardness of cladding plates produced by explosive welding between magnesium alloys having different aluminum concentrations A6005C alloy were investigated. Further, measurements residual stress at the interface performed. In all plates, bonding had a wavy shape. Adiabatic shear bands formed on side deformation twins appeared due to impact welding. Mic...

Corrosion is one of the important factors in equipment failures. Wall thinning can be used to evaluate corrosion conditions. However, most of equipments are coated with insulations in order to elevate the energy efficiency. Pulsed eddy current (PEC) testing technique can be used to measure wall thinning through insulation. But when the insulation outside is wrapped with galvanized steel, PEC si...

Zirconium-based alloys are widely used in the field of nuclear industry as cladding for nuclear fuel in power plants. In a pressurized water reactor (PWR), boric acid is added in the coolant for reactivity control. Lithium hydroxide is added to render the coolant slightly alkaline, which helps to inhibit corrosion product deposition on the fuel cladding and reduces the corrosion rate of structu...

Ni-based alloy powders with different contents of cobalt (Co) have been deposited on a 42CrMo steel substrate surface using a fiber laser. The effects of Co content on the microstructure, composition, hardness, and wear properties of the claddings were studied by scanning electron microscopy (SEM), an electron probe microanalyzer (EPMA), X-ray diffraction (XRD), a hardness tester, and a wear te...

Missing pellet surface (MPS) defects are local geometric defects in nuclear fuel pellets that result from pellet mishandling or manufacturing. The presence of MPS defects can cause clad stress concentrations that are substantial enough to produce through-wall cladding failure for certain combinations of fuel burnup, and reactor power level or power change. Consequently, the impact of potential ...
