Abstract
Cylindrical (carousel) and spherical dome designs for the Large Synoptic Survey Telescope (LSST) were analyzed for air flow characteristics using computational fluid dynamic models. The primary objective was to determine the level of dome flushing achieved with natural ventilation and representative site wind conditions. The domes were 30 meters in diameter at the base, designed to enclose the LSST and provide adequate space for servicing requirements with the smallest possible major dimensions. The carousel style enclosure allowed moderately superior flushing with better uniformity which will produce superior local seeing conditions. Since the cylindrical style enclosure was also determined to be less costly, this concept was chosen as the baseline enclosure design for the LSST.
