LIGHT IRRADIANCE MODEL FOR CHLORELLA FLUID IN ELLIPTIC TUBES
Tubular photobioreactor has been considered as one of the most promising reactor for massive cultivation of Chlorella cells. While, many difficulties exist for the promotion of tubular photobioreactor (PBR), one of them is the large dark area ratio in tubular pipes which are unfavorable for the growth of Chlorella cells. In this paper, the elliptic PBR was introduced. By building the light irradiance model of Chlorella fluid inside elliptic PBRs, the light irradiance distributions inside elliptic PBRs were deduced. Results show that the dark area ratios for both tubular PBR and elliptic PBR increase with the increase of average light absorption coefficient of Chlorella fluid. However, compared with tubular PBR, the dark area ratio of elliptic PBR cross section is much lower under different average light absorption coefficient for Chlorella fluid and the same cross section area, indicating that the elliptic PBRs are of great potential for mass culture of Chlorella in the future.
