| This thesis describes the conception and the study of a photobioreactor dedicated to aquaculture. The state of the art and the technico-economic constraints proper to this activity led to the choices to a simple reactor, volume variable, cheap to produce and reliable for continuous cultures. The elementary module is made of two vertical columns, connected by flanges. An airlift injection located at the base of the column (airlift reactor) generates a swirling flow circulation in order to minimize the biofilm development on the inner side of the column. A pilot of 6.1 liters has been conceived to study the radiative transfers, the hydrodynamics and the biological cultures in continuous mode. Coupling a radiative transfer model (two flux model) with the... |
