Abstract
Light distribution inside algal culture at different incident light intensities (I0=70–350μmolm−2s−1) and biomass concentrations (Cb=0.09 −1.34gL−1) for various configurations of vessels (rectangular and cylindrical) and illuminations (single and even light directions) are investigated and discussed. At Cb >0.5gL−1 the results showed that the influence of I0 is insignificant, particularly at far distances from the illuminated surface, and increasing I0 is not an efficient solution for facilitating photosynthesis in dense cultures. The influence of Cb on light attenuation is strong, especially close to the illuminated surface. Over the first 2cm, the light intensities inside the culture decreased by 35% and 92% when Cb was 0.09gL−1 and 1.34gL−1 respectively. For cylindrical vessel the light distributions in dens culture are quite similar for both one-side and evenly illuminated. Furthermore, new quantitative model has been developed by adapting the Beer-Lambert model to describe light distribution inside algal cultures and predict local light intensity more accurately. The model was able to predict the sharp reduction in light intensity near the vessel surface that B-L model failed to predict; also the model was successfully simulating the experimental results under different conditions.
