About the gauge conditions arising in Finite Element magnetostatic problems

Emmanuel Creusé, Patrick Dular, Serge Nicaise

In this paper, we deal with some magnetostatic models considered in vector potential formulations and solved by a Finite Element solver. In order to ensure the uniqueness of the solution, a gauge condition has to be imposed, and several possibilities occur. Moreover, the source term has to be…

Two Guaranteed Equilibrated Error Estimators for Harmonic Formulations in Eddy Current Problems

Emmanuel Creusé, Yvonnick Le Menach, Serge Nicaise, Francis Piriou, Roberta Tittarelli

In this paper, two guaranteed equilibrated error estimators are proposed and compared for the 3D harmonic magnetodynamic problem of Maxwell's system. This system is recasted in the classical A − ϕ potential formulation or, equivalently , in the T − Ω potential formulation, and it is solved by…

Convergence analysis of a hp-finite element approximation of the time-harmonic Maxwell equations with impedance boundary conditions in domains with an analytic boundary

Serge Nicaise, Jérôme Tomezyk

We consider a non conforming hp-finite element approximation of a variational formulation of the time-harmonic Maxwell equations with impedance boundary conditions proposed in [5, §4.5.d]. The advantages of this formulation is that the variational space is embedded in H 1 as soon as the boundary is…

Using PVDF piezoelectric polymers to maximize power harvested by mechanical structure

Adil Eddiai, Mounir Meddad, Rida Farhan, M’hammed Mazroui, Mohamed Rguiti, D. Guyomar

In recent years, electroactive materials have attracted interest due to its applications in energy harvesting owing to piezoelectric nature. The energy harvesting with these PVDF piezoelectric polymers have great potential to remote applications such as in vivo sensors, embedded micro-electro-…

Design hybridization system of TEG/PZT for power generation: Modelling and experiments

Mounir Meddad, Adil Eddiai, Rida Farhan, Seddik Benahadouga, M’hammed Mazroui, Mohamed Rguiti

Energy harvesting aims to feed portable or fix electrical appliances that can be communicated in order to make them energetically autonomous. This Self-powered is more envisageable as the new electronic technologies available are sober in energy. This study focuses on the generation of electrical…

Evaluation of performance of polyamide/lead zirconate titanate composite for energy harvesters and actuators

Rida Farhan, Mohamed Rguiti, Adil Eddiai, M’hammed Mazroui, Mounir Meddad, Christian Courtois

By means of experimental tools, we have studied the effect of lead zirconate titanate volume fraction introduced in polyamide-6/lead zirconate titanate composites on dielectric, piezoelectric, mechanical, and structural properties. As the first result, we found that the insertion of lead zirconate…
