Outline of Final Research Achievements	We performed the computational fluid dynamics (CFD) numerical simulation for unsteady and non-linear air flow, which is suitable to analyze the air turbulence in the telescope enclosure. The CFD analysis with spatial resolutions of several tens of cm to meters has successfully depicted complex air flows surrounding the telescope. This study suggests that our approach using the unsteady, non-linear CFD analysis is powerful and useful to control and stabilize the air flow in a telescope enclosure.
