微藻类光生物能源利用中的能质转化及调控机制研究

Based on the background of the utilization of microalgae photosynthetic microorganisms energy and mass transition, the spectral radiative properties and transfer mechanism of the algae particles and clusters are studied. The interaction between the radiative field and flow field is analyzed to provide basic physical and theoretical support for the optimal design of the efficient photobioreactor with low energy consumption. The specific contents are as follows: (1) carrying out the theoretical model of spectral radiative properties of algaes, setting up the experimental platform to measure the spectral radiative properties of algaes, and building up the corresponding database of the typical algaes; (2) constructing the accurate multi-dimensional radiative transfer model in the photobioreactor and developing the efficient and accurate numerical algorithm for solving the radiative transfer in different types of photobioreactors; (3) carrying out the analysis of the radiative transfer process coupled with the growth kinetic, the light radiation field and the flow field, investigating the quantitative relationship between the biomass production rate and the incident radiation, analyzing the main factors and the key regulatory factors involving the light energy conversion efficiency, revealing the energy and mass transfer mechanism and regulation mechanism of algae energy. This project involves cross researches of spectral radiative transfer, optics, spectroscopy, biology, computational physics, electromagnetism, materials science and other disciplines, and it is one of the key technologies in biomass energy conversion and utilization.
