Název v původním jazyce

Microalgae cells tracking in hybrid tubular photobioreactor

Popis výsledku v původním jazyce

Mixing of the culture medium in a photobioreactor (PBR) is very important to enhance microalgae cultivation since it ensures that microalgae cells can homogeneously access nutrients and light radiation. In this study, a numerical model of hydrodynamic conditions was developed to investigate the mixing of the culture medium in a hybrid tubular photobioreactor under various operating conditions. Microalgae cells movement in transparent tubes was simulated. The motion of the cells was integrated into a mechanistic model, in order to simulate the influence of operating parameters on the distribution of light in the culture medium and, consequently, on the production of microalgae. According to the developed multi-physical model, when the flow rate of the culture medium increases, more intensive mixing takes place in the transparent area of hybrid tubular PBR, and microalgal cells are more often exposed to light radiation. Mixing intensification showed an increase in microalgal biomass production. However, the increase in production was very low because the concentration of microalgal biomass in the culture medium was generally low and the penetration of incident light in the culture medium was thus not limited.
