1. Advanced Diagnostic Techniques and a Novel Modeling Approach for Photobioreactors in Culturing Microalgae and Cyanobacteria Hu-Ping Luo Washington University Chemical Reaction Engineering Laboratory Advisor: Prof. M.H.Al-Dahhan Nov, 2001 CHEMICAL REACTION ENGINEERING LABORATORY

2. Steep Light gradient Cell movement in the reactor Measured by CARPT technique Problem Description IoIo Depth Dark Center Irradiance field I(x,y,z) External irradiance Cells’ Trajectory Bubbles Accessibility of light, which depends on hydrodynamics, is the control step for the cells’ growth Current studies: Know little about the cells’ movement in the reactor New Approach: Based on the knowledge of hydrodynamics, coupling with knowledge of bioengineering science, to optimize the culturing system.
