The thin shell of the LBT Adaptive Secondary Mirror has been manufactured, optically polished, and delivered. The operations and tests required before finally mounting it on the telescope have to be run very carefully, as they imply loads completely different from the ones of the adaptive operational modes - studied in the past with very encouraging results. Deformations and stresses that occur ...

Microfluidics enables the miniaturization and integration of sensors into advanced analytical devices. Electrochemical detection is currently one of the preferential techniques of use in microfluidic devices due to its sensitivity, low cost and compatibility with new microfabrication techniques. In this work, we first model the electrochemical response of a set of microband electrodes placed ...

The purpose of this study was the optimization of an industrial furnace from a thermal point of view. Such a cylindrical furnace contains an Al-Mg molten alloy covered by a KCl-NaCl molten salt layer floating on it to prevent alloy evaporation. When tilting the cylindrical furnace, it was necessary to compute the relation between the salt and alloy volumes and the area of the liquid alloy/salt ...

The generation 4 of molten salt reactors using the thorium cycle are characterized by a temperature close to 1000 oC. The very large heat transfers involved between the reactor core and the external parts with minimal thermal losses are a major issue. This study investigated a possible inner loop made of a series of conventional graphite filter plate exchangers, pipes and pumps, using the COMSOL ...

In this paper, a simulation of a capacitive flowmeter utilizing a spatial filtering technique is presented. The flowmeter consists basically of ring shaped electrodes placed sequentially in the flow direction on the outside of a pipe. The paper introduces an electrode layout and describes the modeling of the electrodes to achieve the required simulation accuracy.We show the functionality of the ...
