Abstract

The 100-m OWL telescope being considered for open-air operation, wind is an essential disturbance affecting the tracking performance and figure of the primary and secondary mirrors. ESO has undertaken a study to build up a reliable and flexible computer model of the telescope and its environment. This model can, in a cost-effective way, be used to assess the wind loading under different conditions and configurations, before entering into more expensive wind tunnel testing. This paper presents the first preliminary results obtained with Computational Fluid Dynamic (CFD) methods about the wind action on the OWL 100-m telescope, in terms of pressure time histories and in the frequency domain. Preliminary conclusions on the effect of the wind loading on the design are also drafted.
