A research compressor at Seoul National University (SNU compressor) has been built to perform aerodynamic measurements of flow phenomenon occurring inside an axial compressor. The SNU compressor consists of four identical stages including an IGV row. It is an open-type compressor, which is powered by a 55 kW DC motor and a gearbox. Air passes through a bellmouth located the upstream of compressor section, and exits through a downstream throttle which is controlled by four linear actuators to control the flow rate. The SNU compressor uses steady and unsteady sensors such as 5-hole and hot-wire probes to measure the aerodynamic properties inside the compressor. Circumferential and radial measurements are possible by adopting linear traverses and gear system. Pitot probes, RTD sensors, and Kiel probes are installed at the upstream and downstream of compressor to measure the operating parameters with accuracies less than 0.43%.
