微藻光生物反应器中光强分布规律的研究进展

Research Progress of Light Distribution Law in Photobioreactors for Microalgae

光能是微藻生长的唯一能量来源,所以微藻反应器中的光强分布对微藻的生长速率和产量有着巨大的影响。首先综述了由光辐射传递方程求解光强衰减规律的方法,包括不同方法的特点和实用范围,以便根据微藻浓度和反应器的参数选择合适的光强分布的计算方法。其次描述了流场分布对微藻运动轨迹以及微藻接收的光强的影响。

Light is the only energy source for microalgae cultivation, so the light distribution in the photo-bioreactor is important for the growth rate and production of microalgae. Solving methods for the radiative transport equation (RTE) are reviewed in the first place, including the characteristics and applicable conditions of different methods, so as to choose the suitable solving method of the light distribution in photobioreactors with different structures and microalgae concentrations. Secondly, the effects of the flow field on the trajectory of microalgae and thus the light intensity received by microalgae are described.
