摘要：采用CFD技术对敞开式跑道池光生物反应器流场进行了研究,考察了导流板结构、跑道池底部进气孔长度和宽度方向间距对流场的影响规律。结果表明,当内外导流板均为180°、导流板延伸长度ΔL/W为0.5时,跑道池平均速率最大,死区比例最小,功率输入最少;当宽度方向间距ΔY/W1为1/4、长度方向间距ΔX/L1为0.025时,平均光照方向速率最大。采用粒子追踪模型,分别计算不通气与通气情况下粒子的运动轨迹,分析得到藻细胞的光照强度、光暗交替频率。
The flow profile in an open raceway photo-bioreactor was studied by employing computational fluid dynamics （CFD） . The effects of the inducing baffle structure, air inlets spacing along length direction and width direction were investigated. The calculated results showed that an open raceway photo-bioreactor has maximum velocity, minimum dead zone ratio and minimum power input when the inducing baffles angles are 180° , and extending length AL/W is 0.5. The average velocity magnitude along the light direction is maximum when the spacing along width direction AY/Wt is 1/4, and the spacing along length direction AX/L1 is 0.025. Light intensity, light and dark frequency of algal cells are derived from particle trajectories with and without air by employing particle tracking model （PTM）.
