چکیده
Article Type: Full Length Research Article Microalgae have the potential to produce enough biofuels to meet current US fuel demands. In order to achieve this potential, photobioreactors (PBRs) that are efficient, scalable, and affordable need to be developed. Models are an analytical tool that can be used to evaluate various PBRs. In this article, a physics-based dynamic model was developed for growing microalgae in a vertical flat panel photobioreactor that may be used to improve PBR efficiency independent of scale. A model was used to estimate the microalgae growth and by-product production as a function of incident light. A physics-based feed forward controller that uses an estimated amount of CO2 consumption to determine the amount of additional CO2 to be added to the system during photosynthesis, was developed. This was used in conjunction with a feedback controller for growing microalgae inside a PBR.

BACKGROUND Microalgae are a potential source of sustainable commodities of fuels, chemicals and food and feed additives. The current high production costs, as a result of the low areal productivities, limit the application of microalgae in industry. A first step is determining how the different production system designs relate to each other under identical climate conditions. The productivity a...

A dynamic numerical model was developed to predict the biomass concentration, pH, and carbon dioxide fixation rate in the continuous culture of cyanobacteria in a photobioreactor. The model is based on the growth rate equation of microalgae combined with mass transfer equations for gas and liquid phases in the photobioreactor as well as thermodynamic equilibrium of inorganic carbon ions in the ...

The main objective in this research is to explore two separate approaches for improving the growth of microalgae that can be potentially used for producing fuels and chemicals. One approach was to use optical light filters, which selectivity filter natural light allowing certain wavelengths into the culture systems. The other study is to use an algal growth system with different bio-renewable m...

Flashing light effect on microalgae could significantly improve the light efficiency and biomass productivity of microalgae. In this paper, the baffles were introduced into the traditional flat plate photobioreactor so as to enhance the flashing light effect of microalgae. Making Chlorella sp. as the model microalgae, the effect of light intensity and inlet velocity on the biomass concentration...
