Understanding the environment of olive tree cuttings is a key factor in
improving these plants’ rooting rate and survival. This study aims to develop a？three-dimensional (3-D) Computational Fluid
Dynamics (CFD) model for numerically assessing air temperature and
relative humidity in an olive cuttings greenhouse
under Mediterranean climatic conditions. The results are deduced from a steady-state
simulation performed with recorded boundary conditions at 10:00 am,
12:00 pm, 02:00 pm, 04:00 pm, and 06:00 pm at different observation points. The calculations were validated
using experimental data. The simulation errors of the air temperature
were -0.8°C to 4.55°C, and errors of the leaf temperature were 0.07°C
to 2.42°C, for the air relative humidity was-33.84% to -1.64%, and -10.1% to -13.54% for the relative humidity of the leaf air. Contour
maps were obtained from the 3-D CFD simulations to evaluate the distribution of
humidity and air temperature inside the greenhouse and the vicinity of the plant canopy. This study suggests that the
developed 3-D CFD model can be a
helpful tool to understand and
