The microenvironment of the crop area in a greenhouse is the main factor that affects its growth, quality, and pest control.
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 m 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 4–14°C lower and 10%–30% 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 m 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 m 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.
