An eigenvalue as well as a harmonic response analysis is performed on the Gullfaks C, Knock Out Drum (KOD) including some of the connecting pipe systems. The vibration behavior of two new choke valves and their specific connection to the KOD are of special interest. The main concern is the low frequency induced vibration as a consequence of the platform movements. A frequency band between 0-20 Hz ...

The argillite formation has been proposed as a potential host rock for deep radioactive waste disposal. These materials have very low permeability and diffusion is likely to be the predominant transfer mechanism for solute migration.The negatively charged surface of the clays induces unexpected behaviour of the ions: while the anions diffuse slower than HTO, the transport of the cations is ...

Eddy Current Non Destructive Testing is exploited to evaluate the structural integrity of metallic objects. The aim of this paper is to detect defects located in depth within the inspected object; within this framework, we studied the modelling of exciting coils useful to detect structural flaws. The simulations have been carried out by considering the movement of the coil over a structural steel ...

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 ...

We model the liquid transport in foam (i.e. drainage) by unidirectional flow transverse to a triangular planar area that represents channel (i.e. Plateau borders) cross-sections. Partial mobility of the interfaces is obtained balancing the bulk viscous stress with the surface viscous stress and a velocity equal to zero is imposed at the vertices. In liquid foams, the wedges of the channels are ...

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 ...
