Microalgae are a potential solution to supersede fossil fuels and produce renewable energy. The major obstacle to the commercialization of microalgae-based biofuels is the high production cost, including nutritional requirements, photobioreactor design, and downstream processes. As for the photobioreactor design, open ponds have been adopted by major commercial plants for their economic advantages. Raceway is a popular type among open ponds. Nevertheless, the fluid dynamics of the raceway operation is quite complex. Software simulation based on Computational Fluid Dynamics is an upcoming strategy for optimizing raceway design. The optimization intends to affect light penetration, particle distribution, mass transfer, and biological kinetics. This review discusses how this strategy can be helpful to design a highly productive raceway pond-based microalgal culture system.

计算流体动力学（CFD）在微藻培养的管道设计中的应用：综述。

微藻是取代化石燃料和生产可再生能源的潜在解决方案。微藻基生物燃料商业化的主要障碍是高生产成本，包括营养需求，光生物反应器设计和下游工艺。至于光生物反应器的设计，主要的商业工厂已采用开放式池塘来发挥其经济优势。在开阔的池塘中，水道很受欢迎。然而，滚道运行的流体动力学非常复杂。基于计算流体动力学的软件仿真是优化滚道设计的一项即将到来的策略。该优化旨在影响光的穿透，粒子分布，传质和生物动力学。
