ATST Project data • Title: Análisis numérico para determinar la localización del telescopio ATST • Company: Instituto de Astrofísica de Canarias • Period: 01/05/2005 - 31/07/2005 • Collaborators: Joan Baiges, Daniel Pérez
Objectives • To model turbulent air flow around telescope enclosures • To compute pressure spectra • To compute turbulent parameters (integral length and integral time) • To propose a numerical model to compute optical parameters of the site
Key numerical ingredients • Stabilized finite element method • LES turbulence model • Statistical CFD data treatment • Numerical integration procedures along light beams
Results II Pressures. East wind of 1 m/s.
Results III Velocity norm. East wind of 1 m/s.
Results IV Velocity vectors. East wind of Vent 1 m/s.
