Última Mathematical model and numerical simulations of the migration and growth of Biscay Bay anchovy early larval stages ArchiMer Boussouar, Ahmed; Le Bihan, Soizick; Arino, Ovide; Prouzet, Patrick. The paper presents a mathematical model of the early larval stage, from spawn to the resorption of the yolk-sac, of the anchovy, Engraulis encrasicolus, of the Bay of Biscay. The model describes the temperature-dependent growth and drift of passive larvae by the currents and vertical turbulence. A numerical code has been built and numerous simulations, fed by both biological (egg surveys by AZTI-San Sebastian, Spain, and IFREMER, France) and physical (circulation model by IFREMER-Brest, France) data, were undertaken. Their main features are presented and discussed here, and some conclusions on the possible utilization of the results in improving estimates of anchovy stocks by the daily egg production method are drawn.

Ano: 2001 URL: http://archimer.ifremer.fr/doc/2001/publication-518.pdf Étude numérique et expérimentale du comportement d’hydroliennes ArchiMer Mycek, Paul. This manuscript deals with the numerical and experimental characterisation of the behaviour of marine current turbines. In the experimental part, trials were run at IFREMER’s wave and current flume tank in Boulogne-Sur-Mer, on prototypes of three-bladed horizontal axis turbines. Configurations with one single turbine on the one hand, and two turbines aligned with the incoming flow on the other hand, were considered for a large range of TSRs and, when relevant, of inter-device distances. The behaviour of the turbines is analysed in terms of performances (power and thrust coefficients) and development of the wake. The effects of the ambient turbulence intensity rate are also considered. Besides, numerical computations, obtained from a tridimensional unsteady...

L’implantation et le développement de fermes d’hydroliennes sont soumis à la compréhension des effets d’interaction entre machines. Des essais expérimentaux ont été réalisés dans le canal à houle et courant de l’IFREMER à Boulogne-sur-Mer, sur des maquettes d’hydrolienne 3 pales à axe horizontal, dans le but de caractériser les interactions entre deux hydroliennes alignées avec le courant. En parallèle un code numérique tridimensionnel est développé pour modéliser l'écoulement derrière une hydrolienne. Ce code de calcul est basé sur la méthode Vortex. Il permet entre autres de calculer les efforts et moments sur le rotor ainsi que de tracer des cartes de vitesses en aval de l'hydrolienne. La plupart des études numériques portant sur les interactions entre...

Ano: 2012 URL: http://archimer.ifremer.fr/doc/00141/25197/23307.pdf Simulation du comportement d’hydroliennes : modélisation de l’influence de la turbulence ambiante et des effets d’interaction ArchiMer Carlier, Clement. The development of marine current turbines arrays has been an active research topic for some years. However, many studies are still necessary in order to fully understand the behaviour of such arrays. One of these studies is the impact of the ambient turbulence on the behaviour of marine current turbines. Indeed recent studies have shown that ambient turbulence intensity highly modifies the behaviour of horizontal axis marine current turbines. Consequently numerical simulations have to represent the ambient turbulence or at least its effects on the performance and wake of the turbines. An other one of these studies is the assessment of interaction effect between turbines in close proximity. In order to highlight these interaction effects, experiments were...

Ano: 2017 URL: https://archimer.ifremer.fr/doc/00478/58926/61496.pdf Approche experimentale du comportement d'une plaque composite sous effet d'un choc perforant ArchiMer Paris, P; Genin, D; Hamelin, P. Our purpose in this paper is to study the behaviour of composite materials reinforced by glass satin weave 8 fabric under the impact of a projectile. The first part of this paper deals with experimental tests carried out using a servo-hydraulic machine. The hydraulic ram can be programmed to impact the specimen at any desired velocity between a few tenths of a millimetre per minute and 20 m/s. In the second part, these experimental results are compared with the numerical results of bidimensional finite difference code AUTODYN. This program allows the numerical simulation of the penetration of composite plates by projectiles.

Ano: 1992 URL: http://archimer.ifremer.fr/doc/1992/acte-1045.pdf Etude expérimentale et numérique du comportement d’hydroliennes à axe horizontal ArchiMer Carlier, Clement; Mycek, Paul; Gaurier, Benoit; Germain, Gregory; Pinon, Gregory; Rivoalen, Elie. Le développement de fermes d'hydroliennes a suscité et suscite toujours de nombreuses études parmi lesquelles figure l’étude des effets d'interactions entre les machines. Afin de comprendre ces effets d'interactions des essais expérimentaux ont été effectués dans un bassin à houle et courant sur des maquettes d’hydroliennes 3 pales à axe horizontal, régulées en vitesse de rotation. Ces essais portent sur la caractérisation du fonctionnement d’une, puis de deux hydroliennes alignées avec le courant à partir de mesure de performance et de sillage. En parallèle, un code numérique tridimensionnel est développé pour modéliser une ou plusieurs hydroliennes dans un écoulement. On présente ici les résultats numériques et expérimentaux, obtenus pour deux points de...
