摘要:
为加强跑道式光生物反应器中流体在垂直方向流动以促进藻类光合作用,开发了一种连续交错挡板结构,并采用CFD软件研究了连续交错挡板对光生物反应器流场的影响。研究结果表明,增设挡板后,跑道式光生物反应器直通道区域内流体的垂直方向速度明显提升,垂直方向速度大于0.005 m/s的微藻细胞所占比例提高了38%～48%,微藻细胞的光暗循环周期缩短。流体的湍动能和涡量也分别提高了10%和60%左右。交错挡板强化了局部流动,提升了微藻细胞颗粒的上下循环流动效果,对于提高流体混合和促进微藻光合作用帮助较大。
Abstract:
In order to enhance the vertical flow of fluid in the runway type photobioreactor to promote the photosynthesis of algae, a continuous staggered baffle structure was developed, and the influence of the continuous staggered baffle on the flow field of the photobioreactor was numerically studied using CFD software. The results showed that the vertical velocity of the fluid in the straight channel area of the runway type photobioreactor was significantly increased after adding baffles. The proportion of microalgae cells with a vertical velocity greater than 0.005 m/s was increased by 38%—48%, and the light dark cycle of the microalgae cells was shortened. The turbulent kinetic energy and vorticity of the fluid are also increased by about 10% and 60% respectively, strengthening the local flow, and improving the up and down circulation flow of microalgae cell particles, which is of great help to improve fluid mixing and promote photosynthesis of microalgae.
