14-mounth postdoctoral position at SIAME Laboratory (UPPA) in the framework of 2 projects :

• • MiACE-PEF (MicroAlgae Continuous Extraction by Pulsed Electric Field: MiACE-PEF- 4 months) and EXTRA-PEF co-funded by ADEME and PUI Sud Aquitaine Innovation
• • BioACE (Bio Algae Culture Enhancement - 10 month) funded by Institut Carnot ISIFoR

Project descriptions/Duties:

The MIACE-PEF project consists in developing a continuous extraction process demonstrator to obtain extracts from microalgae biomass using pulse electric fields. The overall objective will be to propose an innovative method to extract various bioactive compounds that could be used in a broad range of application fields such as pharmaceuticals, cosmetics, green chemistry, agriculture …

The demonstrator uses the principle of chaotic mixing obtained for the flow of the algal solution within a channel comprising movable wall sections.

The objective is to standardize the residence time distribution in the channel receiving the pulsed electric field so that all microalgae in the solution receive the electric field for equal durations. The aim is to continue the numerical study (CFD) already undertaken in this field to find the range of optimal physical parameters associated with flow/viscosity pairs of the algal solution in order to achieve good uniformity of residence times.

The BioACE project aims to develop a new type of continuous photobioreactor that exploits bioconvective instabilities to intensify microalgae cultivation on a large scale and at high concentrations, with a view to producing biofuels. Stability analyses, numerical simulations, and experiments will be conducted to understand the mechanisms of instability and determine the best geometries and operating conditions for exploiting them.

The work will mainly involve conducting linear stability analyses of 3D flows of the algal solution for specific boundary conditions (wall heating, solar radiation, free surface or not). Additional 3D numerical simulations will also be carried out in collaboration with the CERI EE team at IMT Nord Europe in Douai. This work will enable the selection of experimental geometries that are suitable for microalgae cultivation.

The BioACE project is funded by Inter Carnot ISIFoR/Mines (UPPA and IMT Nord Europe).

The position includes research, write scientific reports and publications and meetings with partners/collaborators.
