Rotating Devices Performing Subsonic Supersonic Flow Transitions
DESCRIPTION OF THE PROJECT
Occurring shock systems in the supersonic flows, e.g. at the leading edge of the turbomachine rotor, reduce the machine efficiency drastically and threaten the responsible use of energy. The project aims at developing a new understanding of the shock establishment and high-frequency response within the rotor. It is divided into an outgoing phase at Purdue University and a return phase at TU Berlin. During the outgoing phase, a numerical analysis of the observed phenomenon will be conducted to develop a reduced model based on 3D characteristics. This model will thoroughly be validated by advanced experimental measurements. Back at the TU Berlin, the final applicability of the reduced model and the functionality of the novel concept will be assessed by a design optimization of a turbine and a compressor geometry.
