Experimental Investigation of an Efficient and Lightweight Designed Counter-Rotating Shrouded Fan Stage [PDF]

International Journal of Turbomachinery, Propulsion and Power
The German Aerospace Center designed, aero-mechanically optimized and experimentally investigated its own counter-rotating shrouded fan stage in the frame of the project CRISPmulti. Their target and the motivation of this work was, on the one hand, the generation of a highly accurate experimental database for the validation of the modern numerical ...

Comparative study on the complex behaviour of flow fields in a transparent non-axisymmetric corotating system between two arm-insertion angles at two measurement planes in an enclosure

Journal of Fluid Science and Technology
Flow driven by co-rotating disks, such as hard disk drives (HDD) have been studied in previous research using axisymmetric models. In our work, a unique non-axisymmetric 3.5" transparent HDD model for information storage was used to investigate the ...

POD-based frequency study of rotating stall in splitter pump-turbines [PDF]

AIP Advances
Rotating stall (RS) compromises pump-turbine stability by inducing strong inter-blade flow separation and low-frequency pressure/velocity fluctuations, especially in the pumping hump region.

A Computational Study of a Novel Turbine Rotor Partial Shroud [PDF]

, 2000
The over tip leakage (OTL) flow that exists between the stationary casing and the rotor tip of a shroudless HP turbine remains a major source of loss of performance for modern aero gas turbines. To-date the principal approaches to reducing OTL loss have

Aerodynamic and Aerothermal Investigation of the Flow Around an HPT Rotor Shroud: Heat Transfer and Cooling Effectiveness

, 2011
An experimental study has been conducted to investigate the aerothermal performance of a shrouded high pressure turbine blade in a large scale rotating rig. The rotor blade and the associated shroud and casing geometry have been modelled in a large scale
