The possibility of extracting water from the air is a possible solution to counter what is the water crisis present in different regions of the world. This study focuses on what is the study of the motion field and subsequent optimization of a water factory located in a desert area. The approach used exploits the use of CFD (Computational Fluid Dynamics) simulations to analyze the momentum, humidity and temperature field, combining this with a spatial optimization process to determine the layout of 16 machines in order to minimize the use of space while ensuring their proper operation. Initially, different physical models are explored in order to validate the reference model (with Outlet parallel to the ground) by varying turbulence patterns, grid settings and values inherent in the turbulence reference quantities.
