Abstract | This study used computational fluid dynamics (CFD) simulations to explore the effect of the greenhouse with the floor and other cooling systems (only an evaporative cooling system, only a floor cooling system, and equipped with both cooling systems) on temperature distributions inside a greenhouse. Three scenarios were analyzed using the finite volume method and several the Realizable k-ε turbulence model offered superior accuracy compared to the Standard k-ε model in simulating temperature distributions. However, significant discrepancies were observed near the wall surfaces of the greenhouse. To address this, a radiation model was incorporated alongside the Realizable k-ε turbulence model, which improved simulation accuracy by reducing error percentages down to 2-3% and better matching experimental results. The study emphasizes the importance of using the Realizable k-ε turbulence model with the radiation model to improve the accuracy of CFD simulations for the greenhouse with the floor and other cooling systems. |
