The growth of horticultural crops is directly affected by the airflow environment in plant factories. In this experiment, a three-dimensional model was established for an indoor artificial light plant factory using computational fluid dynamics (CFD) to simulate the airflow field distribution in the plant factory, the measured value and the simulated value of air velocity were in good agreement, only 10% of the cultivation area was in the range of suitable growth air velocity. The optimization design of airflow field in the plant factory will be developed.
This experiment was developed by Computational fluid dynamics (CFD) technology. A three-dimensional model was conducted for an indoor artificial light plant factory to simulate the temperature field distribution. The results showed that the average absolute error of simulated temperature and measured temperature was 0.7°C, and the average relative error was 3%. The growth indexes of Brassica chinensis in the artificial light plant factory were measured. The uniformity of airflow field in the cultivation area should be further studied for the structural optimization of the plant factory.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
