Modeling and computer simulation of Microalgae photobioreactor

Microalgae is a highly photosynthetic efficiency autotrophic nutritious. It is widely distributed over land and ocean, and is extensively used in fields such as medicine, food, aerospace, biotechnology, environmental protection. As an important equipment, photobioreactor is mainly used in mass cultivation and high-density microalgae. In this paper, we identified and established the mathematical model and computer simulation model of the microalgae growth. The Runge-Kutta method was used to solve the equations on the Matlab platform, in order to verify the accuracy of the model. Based on the mathematical model of microalgae grew under different light intensity and temperature, three-dimensional visualization model was built and implemented in a number of three dimensional software such as 3ds max and Virtools. As a photosynthetic organism, Microalgae is able to efficiently produce oxygen and absorb carbon dioxide. The goal of the visual simulation is to intuitively visualize its change and impact on oxygen and carbon dioxide. We selected different temperatures and light intensities control the photobioreactor, and dynamic change of microalgal biomass, oxygen and carbon dioxide was observed with the aim of providing visualization support for microalgae and photobioreactor research.
