Computational fluid dynamics were used to analyze the flash light effect and CO₂ bubble behavior in an optimized flow field generated by double paddlewheels in a flat plate photoreactor to enhance microalgal biomass productivity. The increased D/w ratio significantly enhanced the average turbulent kinetic energy and flash cycle frequency. However, the effects became weak when the D/w ratio was over 0.67. Appliance of double paddlewheels increased flash cycle frequency from 0.035 to 0.121 Hz and increased light time ratio from 8.3% to 31.5%. Meanwhile, the bubble dynamic behavior was characterized using population balance model. The average bubble size reduced by 24.4% and the bubble rising velocity reduced by 10.6%, which facilitated CO₂ mixing and mass transfer in microalgal solution. Therefore, biomass accumulation of microalgae Chlorella in the photoreactor with double paddlewheels increased by 62.3% under 15% CO₂.

计算流体动力学用于分析平板光反应器中双桨轮产生的最佳流场中的闪光灯效果和CO ₂气泡行为，以提高微藻生物量的生产率。增加的D / w比显着提高了平均湍动能和闪蒸循环频率。但是，当D / w比超过0.67时，效果变弱。使用双桨轮可使闪光循环频率从0.035 Hz增加到0.121 Hz，并且光时间比率从8.3％增加到31.5％。同时，利用种群平衡模型对泡沫的动态行为进行了表征。平均气泡尺寸减少了24.4％，气泡上升速度减少了10.6％，这促进了CO ₂在微藻溶液中混合和传质。因此，在15％CO ₂下，双桨式光反应器中微藻小球藻的生物量积累增加了62.3％。
