The Surface Acoustic Wave (SAW) linear motor was studied which is developed utilizing the friction principle for driving. The principle says that, when a slider is placed on the Rayleigh waves generated on a stator, the slider moves in reverse direction of the wave due to friction between the stator and the slider. A LiNbO3 piezoelectric substrate is used as a stator where comb structured Al ...

Numerical simulation can be advantageously employed to predict the main cell features (e.g., the reaction rate distribution on the electrodes, the cell voltage, or the electrolyte temperature) in order to optimize the design and operational conditions of the process. In this poster, we describe two complementary computational approaches applied to a molten salt electro-refiner for ...

The rotary kiln process is a commonly practiced method in the industry for producing sponge iron using coal. In the industry, there have been recent reports of premature failures of certain air tubes in a rotary kiln. Most of those cases have concentrated on those air tubes which run into the kiln around the middle portion of the kiln. This research work aims at identifying the probable cause of ...

Plasmonic metallic nanostructures have been demonstrated an effective way to enhance the light emission efficiency in LEDs. Here, we propose a design of white LEDs that combining dielectric silicon nanopillar array in the color-converting layer. By investigating theoretically the guided mode caused by the nanopillar array-waveguide system, we demonstrate that the silicon nanopillar arrays enable ...

Permanent Magnet Flowmeter (PMFM) is a non invasive device, which is used to measure the flow of electricallyconducting sodium in Fast Breeder Reactor Circuits. PMFM works on the principle of generation of motional EMF by magnetic forces exerted on the charges in a moving conductor. In this paper modeling of PMFM with different pipe sizes is done to predict the flowmeter output for a given ...

One of the crucial topics in this century is sustainable energy. In this respect, the exploitation of geothermal energy from deep hot aquifers becomes opportune. Hence, insight is required in the heat balance of potential aquifer systems. Essential issues are convection, conduction and dispersion. This article focuses on Lauwerier’s problem. As an extension, it is suggested that beside ...

We study the gravity-driven film flow of a Newtonian liquid down an inclined plane. Many applications such as heat- and mass exchangers and evaporators or film coaters require undulated or rippled bottom topographies. In these cases, the interplay of gravity, surface tension and inertia leads to a response of the interface which furthermore strongly depends on the shape of the bottom topography. ...

Dynamic measurement of magnetic particles in continuous flow devices is made very difficult by the limitations imposed by the sensors themselves. Thus, certain sensor layouts are restricted to either number sensitive or spatial resolutive measurements of magnetic particles. We investigate different new strategies to increase the detection threshold and introduce designs accomplishing both: ...

Mathematical optimization can be used as a computational engine to generate the best solution for a given problem in a systematic and efficient way. In the context of monolithic converter systems, the parameter estimation problem (or inverse problem) is solved using Partial Differential Equations (PDE)-based models of the physical system coupled with an optimization algorithm. These problems are ...

Nerve localization is important for applications in regional anesthesia. Localization is achieved by stimulating the nerve with an electric field produced by a current from a needle inserted into the body of the patient, close to the target nerve. Modeling of the electric field in close proximity to the nerve may help to explain observed variations in threshold currents and can help to ...
