Abstract:

The experimental investigation was performed for votex generator jets (VGJs) controlling flow separation occurred in the suction side of low pressure turbine at low Reynolds number conditions. The experiments were conducted on the lowspeed linear cascade tunnel at Northwestern Polytechnical University (NPU). Cases at Reynolds numbers ranging from 19 000 to 260 000 were considered at the freestream turbulence intensity about 1%.
