Simulation of the light evolution in an annular photobioreactor for the cultivation of Porphyridium cruentum

▸ An integrated model for the cultivation of microalgae including flow, radiation and microorganism growth is presented. ▸ The evolution of light transfer in the photobioreactor (PBR) is well captured both in the batch and continuous cultures. ▸ The radiation of two polychromatic light sources is successfully predicted by the box model and corrected light/dark ratio.
