Resumen:
The set up of a large telescope requires a previous comprehensive study of the local meteorological and seeing conditions. The south ridge of mount Mac ́on, province of Salta, Argentina has been studied for more than a year and good seeing conditions have been found. However, strong wind conditions drastically affect the selection of the best place where a large telescope may be installed. In the present work, a CFD (Computed Flow Dynamic) study is performed to analyze the wind speed distribution and flow pattern over the site. A GPS based high resolution topographical model was developed. The numerical formulation is a large eddy simulation (LES) of the incompressible Navier-Stokes equations approximated using the finite element method and results are confirmed with the experimental measurements.
