Projets et Porteurs  Description

Analyse du stress des microalgue

Philippe MOULIN (Laboratoires M2P2  & IUSTI)

The aim of this work is to carry out a global study from the rheological properties of microalgae suspensions to a microfiltration membrane process. The aim is to determine under which operating conditions the microalgae could break. The integrity of these microalgae suspensions is evaluated as a function of the operating conditions using X ray tomography, TEM and MEB. The complementary aspect of these techniques should allow the determination of average but also individualized information about microalgae.


Philippe LASAYGUES (Laboratoires LMA & IRPHE)

The project is part of a collaboration between the laboratories, LMA, IRPHE, LAMPEA (Aix-en-Provence), CEPAM (Nice, Sofia Antipolis) and the LC2R (Draguignan). It concerns the characterization of human and animal bones for applications in archeo-anthropology (study of ancient and paleolithic funerary rites) and zoo-archaeology (study of conservation in taphonomy, and paleolithic strategies of subsistence by bone fracturing). There is a large literature on the identification of the physico-mechanical properties of different elements and portions of human or animal bones with a recent or short postmortem interval, but very few studies, other than densitometry, on prehistoric human or animal bones. It is a challenge for the acoustic engineering and paleo-archaeology communities to study these bones.


Diogo CAMELLO BARROS (Laboratoire IUSTI)

During the cold spray process, micron-sized particles are accelerated by a supersonic nozzle and projected onto a substrate for coating purposes. Due to their relatively large size in a high-speed turbulent flow, particle inertia plays a fundamental role in the process. A detailed knowledge of the gaz/particle velocity fields is hence essential for the prediction of the particle deposition rate. This project aims to provide, for the first time in this flow, coupled gaz/particle measurements by the use of twocolor particle image velocimetry.

Réponse d’un décollement ouvert à une excitation acoustique en écoulement 

Sébastien PIPONNIAU (Laboratoires IUSTI & IRPHE)

This project aims to study the unsteadiness of Shock wave boundary layer interactions when the boundary layer does not reattach downstream. Based on an original experimental setup in supersonic flow, previous studies have shown that the separation shock unsteadiness does not exhibits low frequency unlike classical interactions but seems to behave like a low-pass filter and amplifier of the perturbations generated in the subsonic external flow. By means of acoustic control of the subsonic region, the response of the interaction to harmonic disturbances will be explored.


Cédric PINHEDE (Laboratoire LMA)

Proteus, one of the oldest cave-dwelling species, exhibits remarkable adaptations on several levels. The objective of this project is to highlight its auditory faculties by carrying out several measurement campaigns at the Theory and Experimental Ecology Station (SETE). Acoustic and vibration measurements will then be carried out on the site. At the same time, simulations will be developed from 3D images taken with a micro-tomograph in order to have a prediction tool.
