Paper Abstract

Recent advancements in computational fluid dynamics (CFD) software now make it possible to perform a full three-dimensional turbulent air flow analysis without the need for a supercomputer. The presented study investigates the airflow effects over 2-meter TSU telescope using CFD method. The effects of air velocity, air pressure about statics and dynamics and K energy have been calculated by using multi-physical coupling theory and CFD methods. It is shown that 90° angle between main optics axis and horizontal line is the best observation direction in which the air velocity distribution, airflow pressure deformation and K energy are the least to other directions.
