This study aims to develop 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 -0.8ˇăC to 4.55ˇăC, and errors of the leaf temperature were 0.07ˇăC to 2.42ˇăC, 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 %K Numerical Simulation %K Computational Fluid Dynamics %K Greenhouse %K Microclimate %K Olive Cuttings %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=113750
