Project Details
Active flow control of stator cascades at periodically-transient boundary conditions (B01)
Subject Area
Hydraulic and Turbo Engines and Piston Engines
Term
from 2012 to 2021
Project identifier
Deutsche Forschungsgemeinschaft (DFG) - Project number 200291049
The project aims to transfer the results of the previous funding periods for active flow control in compressors to realistic engine conditions. For this purpose, experimental investigations are carried out on two high-speed test rigs in order to develop an actuator system, which can be used in the relevant Mach number regime of up to Ma∞= 0.6 upstream of the compressor cascade. By means of numerical flow simulations, fluidic actuators are designed for application in highly compressible flows with the aim of adapting the actuator characteristics to turbomachine-like flow conditions. Subsequently, the effect of the whole actuator system for flow control with an adjustable throttle valve will be used in a full-scale annular test rig under representative periodically unsteady flow conditions.
