Tubular Photobioreactors (PBR) present better productivity using static mixers but they consume large amounts of energy. In this study, a tubular PBR is presented with a new static mixer that produces swirl mixing, inducing light–dark (LD) cycles, and adequate uptake of nutrients in the culture. This study was focused on diminishing the pumping energy required for culture transport while improving productivity by the development of LD cycles in microalgae culture.

管状光生物反应器的静态混合器提案，可减少混合能量消耗并增强明暗循环

管状光生物反应器（PBR）使用静态混合器具有更高的生产率，但它们消耗大量能量。在这项研究中，提出了一种管状PBR和一种新型静态混合器，该混合器可产生涡流混合，引起明暗（LD）循环，并充分吸收培养物中的养分。这项研究的重点是通过开发微藻培养中的LD循环来减少培养物运输所需的泵送能量，同时提高生产率。
