Abstract:

In this contribution, the commissioning of the Closed Loop Organic Vapor Wind Tunnel (CLOWT) is discussed and first operational experience of this test facility is presented. The paper comprises four parts. In the first part, the low-speed aerodynamics of CLOWT, based on measurements with Constant Temperature Anemometry (CTA) and Pitot-Static Tubes, is analyzed. Due to the fact that CLOWT acts as a pressure vessel system, leakage issues are of fundamental importance for this facility. For this reason, in the second part, both static leakage tests (without shaft rotation) and dynamic leakage tests focusing on the shaft sealing are discussed. CLOWT follows the concept of a continuous running mode. Therefore, in the third part, the thermal longterm behavior is considered, while time-dependent temperature and pressure measurements inside the test section are shown. In the last part, the compressor performance is presented. Based on the commissioning and first operational experience, an outlook for future experiments with organic fluids is given.
