Glass products are widely diffuse in the everyday reality. An interesting glass application field, from a technological point of view, is the transportation area. The automotive industry always needs for more complex shape of windscreen in order to satisfy the request of new design. In the paper, a “common” windscreen forming process, for automotive application, is described. The results of a ...

We study the spin wave excitation (coherent precession of magnetic moments) in periodically arranged magnetic stripes, i.e., in one-dimensional magnonic crystal (MC). Two approaches have been implemented. We have defined a structure that dispersion relation can be obtained using both approaches and compared them. In general, the approach I has to be used for MCs where the exchange interactions ...

The most commonly used type of resonator is the AT-cut, where the quartz blank is in the form of a thin plate cut at an angle to the optic axis of the crystal. This paper reports the modeling of a quartz oscillator for a resonant frequency analysis based on piezoelectric effects. The proposed oscillator consists of a single quartz disc with two electrodes on the top and bottom surfaces of the ...

The Large Eddy Simulation is an important method to simulate turbulent flow. It does not produce a closed system of equations, to achieve this it is necessary to model the not-closed terms. The deconvolution can be used for this purpose. In this study some numerical experiments on this topic are performed with COMSOL Multiphysics®. The main objectives are to find an efficient way to implement ...

To obtain reliable kinetic data for the modeling of Dried Distiller’s grains with Soluble (DDGS) gasification using a 100 kWth steam-O2 blown circulating fluidized bed (CFB) gasifier, the combustion behavior of partially gasified residual DDGS char and pure charcoal as a comparison has been investigated using thermogravimetric analysis (TGA). Two conversion models, volume reaction model (VRM) ...

Optimization of a typical electrochemical system with insulating shields is considered in this work, which objective is to reduce the current peak due to singularity and smooth the current density distribution along electrode surface. Moving mesh method was adopted to allow change in design variables, i.e., position and width of the insulating shields. It was found that combining optimization ...

Methane detection and quantification is of great importance due to its natural abundance, potential to cause explosions and known greenhouse effect. Leak detection and concentration monitoring at source is highly challenging as CH4 is odorless and colorless. This can be performed mounting sensor network over a potential diffusion area. It requires optimal positioning of those sensor nodes to ...

In the last decades, the topic of microfluidic Electroosmotic Pumps (EOP) gained the attention of scientists all over the world. One of the greatest advantages of the electroosmotic pumps is the fact, that there are no moving parts. With the effect of electro osmosis, it is possible to generate a continuous, bi-directional, impulse-free stream of electrolyte fluid. This effect leads to a high ...
