Preliminary Experimental and CFD Results on Airflow and Microclimate Patterns in a Closed Greenhouse

Use of computational fluid dynamic tools to model the coupling of plant canopy activity and climate in greenhouses and closed plant growth systems: A review

“…They also predicted that in the middle and lower parts of the crop, the latent heat associated with transpiration was higher than the received radiative energy, meaning that the leaves cooled the air at these levels. within the crop cover at noon (after Pouillard et al, 2012).…”

CFD determination of the climate distribution in a semi closed greenhouse with air cooling

“…This energy balance was solved by means of a specially developed user defined function (UDF) (Boulard and Wang, 2002). The governing laws for crop cover exchanges together with the boundary conditions have been described in a previous paper (Pouillard et al, 2011) for momentum, heat and water vapour. The resolution of these conservation equations was performed with the CFD code Fluent v.15.0 that permits the determination of pressure, velocity, temperature and water vapour concentration for every mesh node.…”

“…Experimental facilities have been developed in the CTIFL Experimental Center of Balandran in South France, consisting of a semi-closed greenhouse connected to an aquifer thermal energy storage system that allows the use of stored thermal energy in the winter period (Grisey et al, 2011). Concerning the inside climate distribution, both experiments and CFD simulations have been performed and the first results regarding the distribution of temperature and humidity have been presented in a former paper (Pouillard et al, 2011). Measurements and simulations of the evolution of the CO2 concentration have also been performed for a summer day with the use on a photosynthesis model of the crop (Roy et al, 2013).…”
