摘      要：In this study,the evaluation of the performance of the split internal loop photobioreactor for culturing a species of green microalgae,Scenedesmus *** different operating superficial gas velocity and during a different time of growth(i.e.,starting for the first day until end day of the culturing process)was *** evaluation of the performance of the split internal loop photobioreactor was included assessing the density,pH,temperature,viscosity,surface tension,the optical density,cell population,dry biomass,and chlorophyll of the culture medium of the microalgae ***,the hydrodynamics of a Split Internal-Loop Photobioreactor with microalgae culturing was comprehensively *** particle tracking(RPT)and gamma-ray computed tomography(CT)techniques were applied for the first time to quantify and address the influence of microalgae culture on the hydrodynamic *** hydrodynamics parameters such as local liquid velocity field,shear stresses,turbulent kinetic energy,and local gas holdup profiles were measured at different superficial gas velocities as well as under different times of algae *** obtained results indicate that the flow distribution may significantly affect the performance of the photobioreactor,which may have substantial effects on the cultivation *** obtained experimental data can serve as benchmark data for the evaluation and validation of computational fluid dynamics(CFD)codes and their ***,in turn,allows us to develop efficient reactors and consequently improving the productivity and selectivity of these photobioreactors.
