Advance Of Environmental Control In Plant Factory Based On Computational Fluid Dynamics

Plant factory is the senior form of modern agriculture. Plant factory were widely used in scientific research and actual production due to their high-precision control, high-efficient land utilization, water saving, fertilizer and pollution-free. This study summarized the research progress of the plant factory from three main aspects: the development of the plant factory industry, the environmental regulation for plant growth. the application of computer fluid simulation technology in plant factory. With the indepth research of scholars and development of economy, the plant factory has received extensive attention in many countries. Worldwide, the present environmental control technologies include the regulation of temperature. humidity. and carbon dioxide in plant factory. These technologies are relatively mature and can meet the requirements of scientific research and actual production. Computational Fluid Dynamics technology was widely used in agriculture, and mainly focuses on the simulation of microclimate in solar greenhouses, particularly the ventilation, The position, quantity, and angle of the inlet and outlet were taken as the entry points for most studies to the ventilation simulation for plant factory. This study aims to provide useful information for further research on environmental regulation of plant factory.
