The high speed cascade wind tunnel (HGK) of the Institute of Jet Propulsion at the Universität der Bundeswehr München is a well-known test facility among experts in the turbomachinery world. It was first installed at DLR in Brunswick before it moved to Neubiberg in , where it was heavily refurbished, rebuilt, and extended.

An experimental and numerical investigation on the flow separation in the corner between a wall and a vane in a highly loaded compressor cascade was performed. A large part of the total losses of a compressor stage is caused by this. At transonic velocities ( cascade wind tunnel in order to avoid or to reduce shock wave reflections and choking of the wind tunnel.

The Reynolds number was varied from to 1 to capture the operating regime for heavy-duty gas turbines. Four different types of surface roughness on the same profile were tested in the High Speed Cascade Wind Tunnel of the University of the German Armed Forces Munich and evaluated against a hydraulically smooth reference by: The validation data of this low pressure turbine (LPT) cascade have been obtained at the High Speed Cascade Wind Tunnel of the Institute of Jet Propulsion.
For this purpose, experiments were conducted within the range of Re 2 th = 40, toTo gather data at realistic engine operation conditions, the wind tunnel allows for an Cited by: 2.

The investigated compressor cascade called V– was designed for the hub section of a stator blade in a highly loaded axial compressor (Hoheisel ).The design conditions with an inlet Mach number of Ma 1 = and an inlet flow angle of β 1 = ° lead to a fully subsonic cascade flow.

No. 1 Modified Crocco-Lees Mixing Theory for Supersonic Separated and Reattaching Flows. Im Hinblick auf die besonderen Betriebsbedingungen von Flugzeug-Turbinentriebwerken wurde der Einfluß der Profildicke auf die Strömungsvorgänge in ebenen Verdichter-Schaufelgittern in einem großen Bereich von Reynoldszahlen und im gesamten Machzahlbereich der Unterschallströmung untersucht.

The test stand serves as a pilot facility to develop tools for analogous investigations in transonic flow. Eleven blades are elastically suspended in a windtunnel with a 1 × m 2 cross section.

This is a theoretical study about ice particle impact onto a rigid wall. It is motivated by the need to model the process of ice crystal accretion or damage caused by an ice particle impacts.
The experiments are performed at the Transonic Cascade Wind Tunnel of DLR in Cologne. The inflow Mach number during the tests is and the AVDR [1, 2] is adjusted to (design value). Bei Strahltriebwerken tritt in sehr großen Flughöhen wegen der kleinen Reynoldszahlen, bedingt durch die laminare Ablösung der Strömung an der Schaufeloberfläche, häufig eine erhebliche Verschlechterung des Wirkungsgrads auf.
Diese läßt sich jedoch durch eine Erhöhung der Turbulenz der Strömung teilweise vermeiden. Zu diesem Zweck erhöhte man einmal den Turbulenzgrad in der. Sturm.L. Fottner, The High-Speed Cascade Wind Tunnel of the German Armed Forces University.

The book reports on the latest theoretical and experimental advances in the field of active flow and combustion control. It covers new developments in actuator technology and sensing, in robust and optimal open- and closed-loop control, as well as in model reduction for control.
It collects contributions presented during the third edition of. The book focuses on rigorous mathematical derivation of the equations governing flow and detailed descriptions of the numerical methods used to solve the equations. Numerous applications of the methods to different types of turbomachine are given and, in many cases, the numerical results are compared to experimental measurements.
This paper develops an analytical model to investigate the aerodynamic of the power generation of a linear cascade wind turbine, referred to as PowerWindow. Schmitz, F.
