The coupling of hydrodynamics with biological models adds advection and diffusion of some quantities that are already characterized by reaction terms expressing their growth or respiration. The analysis and simulation of such models is complex since nonlinearities are important and the time constants in biology are fare greater than those of hydrodynamics. Recent advances have been performed on the subject. The video below shows a typical raceway containing algae, whose water is driven into motion by a paddlewheel. It
This work is done as part of the Institut d’Excellence Energies Décarbonées (IEED « GreenStars ») for the production of microalgae aiming at energy delivery. But we are also
