Dynamic Growth Rate Model Has Been Developed to Quantify the Impact of Hydrodynamics on the Growth of Photosynthetic Microorganisms and to Predict the Photobioreactor Performance. Rigorous Verification of Such Reactor Models, However, is Rare in the Literature. in This Part of Work, Verification of a Dynamic Growth Rate Model Developed in Luo and Al-Dahhan (2004) [Biotech Bioeng 85(4): 382-393.] Was Attempted using the Experimental Results Reported in Part I of This Work and Results from Literature. the Irradiance Distribution Inside the Studied Reactor Was Also Measured at Different Optical Densities and Successfully Correlated by the Lambert-Beer Law. When Reliable Hydrodynamic Data Were Used, the Dynamic Growth Rate Model Successfully Predicted the Algae's Growth Rate Obtained in the Experiments in Both Low and High Irradiance Regime Indicating the Robustness of This Model. the Simulation Results Also Indicate the Hydrodynamics is Significantly Different between the Real Algae Culturing System and an Air-Water System that Signifies the Importance in using Reliable Data Input for the Growth Rate Model. © 2011 Wiley Periodicals, Inc.
