The presence of a moving fluid in a porous rock modifies its mechanical response. Poroelasticity explains how the fluid inside the pores bears a portion of the total load supported by the rock. The remaining part of the load is supported by the elastic skeleton, which contains a laminar fluid coupled to the framework by equilibrium and continuity conditions. This work introduces an original ...

Deformable image registration is a form of medical image processing that can provide insights into the development of phenomenon and variation in normal anatomical structure over time. Prior to post-operative pleural photodynamic therapy (PDT), a series of CT scans of lungs will be acquired. During PDT treatment, an infrared navigation system is used to contour the lungs and provide real-time ...

This paper deals with a numerical modelling technique based on finite elements method for computing magnetic field and current density distributions in high temperature Superconducting (HTS) tapes. The model is developed using the T-ῼ formulation for which the degree of freedom (DOF) and the CPU time decreased considerably in AC losses analysis, and it is also observe that T-ῼ formulation ...

Direct realization of absorbed dose to water in diagnostic radiation via calorimetric methods poses many challenges since the thermal signal of interest may be less than a few microKelvin. In actual biological systems or structures, like the lung, there is the additional complication of tissue heterogeneity, which introduces a quasi-random component to the dose distribution, hence to thermal ...

Research at Fraunhofer EMI addresses the response of materials in extreme dynamic loads. Besides mechanical or thermal loads, intense electric pulse currents also represent an extreme dynamic load. Experimentally, metallic samples, mainly thick wires, were electro-mechanically loaded with currents up to 400 kA. For this purpose, a test rig containing a high-voltage pulsed power supply and ...

Surface aeration systems are used in the wastewater treatment industry for the transfer of oxygen in the activated sludge process. These systems are capital intensive and also require a significant amount of energy to operate. Scale-up and design of these systems is largely empirical, and due to the size of these systems, modifications for experimental testing can be economically prohibitive. ...

Ferrofluids have been successfully used in the seals for rotary shafts, but few studies focus on the reciprocating motion seals. Since the completely different operational regimes, previous experiences on the rotary motions could not be directly applied on the cases for reciprocating shafts. In this study, we present a simplified model to describe the process that a shaft linearly moving in a ...

Corona discharge is used in several applications such as surface treatment of polymers, photocopying or dust removal in air conditioning. Streamer formation is undesirable for most of these applications. Therefore, several studies have been dedicated to investigate the formation and propagation of streamers, which are still not fully understood. The most suitable models to describe streamers are ...

In this paper, after a brief presentation of our company, we will detail our technology and the importance of the simulation step. In the same time, we will describe different levels of FEA (Finite Element Analysis) we have followed and we will conclude on the best balance, for our industrial target, between complexity of models and accuracy of results.
