Dynamic modelling of microalgae growth under micro-aeration conditions

Microalgae cultivation is a critical prerequisite of biomass and biofuels production, which is conductive to the reduction of fossil energy consumptions, but there are the hydrodynamic challenges. This study proposed a dynamic modelling of microalgae growth using experimental and computational fluid...
