, 1992 Turbine blades are usually pretwisted and have asymmetric cross sections. Furthermore, turbine blades are formed into packets by joining them at critical locations with shrouds or lacing. Such a procedure alters the vibration characteristics of the blade.

Rotating Instabilities in a Radial Vaneless Diffuser
, 2010 The paper reports on the flow field in a vaneless diffuser of a radial flow pump at partial flow conditions. Experimental data were obtained within the diffuser using 2D/3C high repetition rate PIV coupled with unsteady pressure transducers. The pressure

Formation and evolution of Rayleigh-Bénard streaks in rotating cavities
, 2018 This paper presents numerical investigation into the phenomena of so-called Rayleigh-Bénard streaks inside rotating-cavities. Experimental data from the University of Sussex Multiple Cavity Rig (MCR) has been used as boundary conditions for Unsteady ...

Large-eddy simulation of buoyancy-induced flow in a sealed rotating cavity [PDF]
, 2018 Buoyancy-induced flows occur in the rotating cavities of gas turbine internal air systems, and are particularly challenging to model due to the inherently unsteadiness of these flows.

Drag Reduction Effect of Gradually-Varying Riblet Structures on Conical Rotating Disks
水下无人系统学报Based on the enclosed flow field conditions and optimized dynamic-static clearances, a gradually-varying riblet drag reduction structure was proposed by combining the drag reduction principle of uniform-sized riblets to address the problem of increased ...

Extension of the Rotating Disk Electrode Method to Thin Samples of Non-Disk Shape
, 2019 A straightforward approach is presented to make thin electrode samples of non-disk shape compatible with the rotating disk electrode method, by merely attaching the sample on the rotating shroud and confining the area exposed to the electrolyte using ...

FREQUENCIES AND MODES OF ROTATING FLEXIBLE SHROUDED BLADED DISCS-SHAFT ASSEMBLIES
TASK Quarterly, 2003 It is now increasingly necessary to predict accurately, at the design stage and without excessive computing costs, the dynamic behaviour of rotating parts of turbomachines, so that resonant conditions at operating speeds are avoided. In this study, global rotating mode shapes of flexible shrouded bladed disc-shaft assemblies are calculated.
