Vibration characteristics analysis of rotating shrouded blades with impacts
Journal of Sound and Vibration, 2016Abstract A dynamic model of rotating shrouded blades with impacts among adjacent shrouded blades is established considering the effects of the centrifugal stiffening, spin softening and Coriolis force, and the model is validated using finite element method.

Volume 2A: Turbomachinery, 2015
A potential means of significantly reducing the cavity exit mixing loss, a dominant primary loss mechanism in turbine tip shroud cavity flow, is assessed. The operational constraints on the turbine stage dictate that losses may only be mitigated through configuration changes within the cavity. A configuration, known herein as the Hybrid Blade, features

Heat Transfer to an Actively Cooled Shroud With Blade Rotation
Journal of Thermal Science and Engineering Applications, 2015An experimental study of the shroud heat transfer behavior and the effectiveness of shroud cooling are undertaken in a single-stage turbine at low rotation speeds. The shroud consists of a periodic distribution of laterally oriented cooling holes that are angled at 45 deg to the shroud surface in a repeating circumferential pattern and has five unique ...

Fluid trapping by two partially shrouded rotating cylinders
Journal of Fluids and Structures, 2014Abstract In this paper we examine the prospect of using localized flow control for biomimetic fluid trapping. The problem is of interest for applications that call for guided transport of fluid volumes. The study shows that trapping can be achieved with the help of two partially shrouded rotating cylinders in a side-by-side arrangement.

Low noise and rotating fan and shroud assembly
The Journal of the Acoustical Society of America, 1993The present rotating fan and shroud assembly reduces noise emitted therefrom and increases cooling system efficiency. The rotating fan and shroud assembly when combined with the labyrinth-type seal also improves serviceability and reduces maintenance time and cost.

Acoustics of a counter-rotating shrouded propfan - Prediction and data
Journal of Aircraft, 1995The acoustic characteristics of a counter-rotating integrated shrouded propfan are studied both theoretically and experimentally. The calculation method comprises the main noise generation mechanisms of the propulsor as steady rotor blade loading noise, rotor/rotor and rotor/struts interaction noise, inlet flow distortion noise, and broadband noise. It

On the flow between two rotating shrouded discs
Computers & Fluids, 1986Abstract Numerical solutions to the full Navier Stokes equations for the flow enclosed between two rotating discs and a sidewall are presented. The sidewall remains fixed throughout, while we consider examples in which: (i) the bottom disc is rotating and the top disc is fixed; (ii) the two discs rotate in the same sense; (iii) the two discs rotate ...

Heat Transfer to an Actively Cooled Shroud With Blade Rotation
Volume 5B: Heat Transfer, 2014In this paper, an experimental study of the shroud heat transfer behavior and the effectiveness of shroud cooling under the conditions of rotation is undertaken in a single stage turbine at low rotation speeds. The shroud consists of a periodic distribution of cooling holes that are 1 mm in diameter (D).
