In this study, we propose a double-layer film solar greenhouse microenvironment testing system based on computational fluid dynamics simulations of a celery canopy with a porous medium. A real greenhouse was examined with a sensor system for soil, air, radiation, and carbon dioxide detection to verify the simulation results. By monitoring the internal environment of celery canopies with heights of 0.8 and 1\u2009m during a period of temperature fluctuations, we found the temperature and humidity of the canopy interior changed spatially and differed greatly from the those in the greenhouse under solar radiation conditions. The temperature and humidity of the celery canopy were 4\u201314\u00b0C lower and 10%\u201330% higher than those of the surroundings. As the canopy grew, the differences in temperature and humidity between the canopy and other parts of the greenhouse increased. The root mean square errors of the temperature and humidity with the 0.8\u2009m high celery canopy were found to be 0.56 and 2.86 during the day and 0.24 and 0.81 at night, respectively; the corresponding values for the 1\u2009m high celery canopy were found to be 0.51 and 2.26 during the day and 0.26 and 0.78 at night. The porous medium model expressed the temperature and humidity characteristics of the celery crop appropriately, and the simulation method was shown to be effective and feasible. With the simulation method proposed in this study, the production of crops in complex microenvironments in greenhouses can be modeled and digitized.<\/jats:p>","DOI":"10.1155\/2020\/8874468","type":"journal-article","created":{"date-parts":[[2020,10,18]],"date-time":"2020-10-18T00:50:08Z","timestamp":1602982208000},"page":"1-15","source":"Crossref","is-referenced-by-count":23,"title":["Computational Fluid Dynamics-Based Simulation of Crop Canopy Temperature and Humidity in Double-Film Solar Greenhouse"],"prefix":"10.1155","volume":"2020","author":[{"given":"Wei","family":"Jiao","sequence":"first","affiliation":[{"name":"College of Mechanical and Electrical Engineering, Inner Mongolia Agricultural University, Hohhot 010018, China"},{"name":"Institute of Grassland Research of CAAS, Hohhot 010010, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qi","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Mechanical and Electrical Engineering, Inner Mongolia Agricultural University, Hohhot 010018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lijun","family":"Gao","sequence":"additional","affiliation":[{"name":"College of Mechanical and Electrical Engineering, Inner Mongolia Agricultural University, Hohhot 010018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kunyu","family":"Liu","sequence":"additional","affiliation":[{"name":"Institute of Grassland Research of CAAS, Hohhot 010010, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rui","family":"Shi","sequence":"additional","affiliation":[{"name":"Collage of Grassland, Resources and Environment, Inner Mongolia Agricultural University, Hohhot 010018, China"},{"name":"Baotou Medical College, Baotou 014040, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1348-5655","authenticated-orcid":true,"given":"Na","family":"Ta","sequence":"additional","affiliation":[{"name":"College of Mechanical and Electrical Engineering, Inner Mongolia Agricultural University, Hohhot 010018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"crossref","first-page":"129","DOI":"10.1016\/j.compag.2009.05.004","article-title":"Numerical modelling of temperature variations in a Chinese solar greenhouse","volume":"68","author":"G.
