| Popis: | Microalgae are organisms capable of synthesising compounds, such as proteins, lipids and carotenoids, which have several applications in food industry. Photobioreactors are a class of closed systems capable of providing an adequate process control for the cultivation of these organisms. Electrical treatments are a novel technology which can be applied in microalgae to enhance both the extraction of some compounds of interest, as well as its cell growth rate. A numerical methodology is proposed to model the hydrodynamics of an airlift photobioreactor with the application of a moderate electric field. The computational model was validated by comparing to two other works found on the literature. The temperature and the current density distributions were obtained for four different sets of boundary conditions. The numerical methodology proposed has shown to be adequate to describe the hydrodynamic behaviour of the photobioreactor. |
