Windage Heating in a Shrouded Rotor-Stator System
Journal of Engineering for Gas Turbines and Power, 2014This paper has experimentally and numerically studied the windage heating in a shrouded rotor-stator disk system with superimposed flow. Temperature rise in the radius direction on the rotating disk is linked to the viscous heating process when cooling air flows through the rotating component.

Parallel Computation of Rotor-Stator Interaction
1998Numerical simulation of rotor-stator interaction is crucial for turboma-chinery improvement since it allows the optimization of blade path design. In addition, the numerical simulation of rotor-stator interaction makes it possible to predict the location and variation of hot spots on blades, which is extremely useful in the turbine thermal design ...

An analysis of rotor-stator interaction
2012The aim of this paper is to investigate the influence of rotor-stator interaction on the dynamic behaviour of a rotor-bearing system. First the model of a SDOF system with two stop-ends is established. The analytical solution permits testing the stability and the robustness of the penalty contact law combined with two numerical schemes. Second, a three-

Experimental investigation of enclosed rotor-stator disk flows
Experimental Thermal and Fluid Science, 1994Detailed hydrodynamic measurements were obtained in a rotating water-flow rig for an enclosed rotor-stator system with a stationary outer shroud. Three different measuring techniqueslaser-Doppler anemometry, hot-film velocimetry, and the yaw-tube methodwere employed.

Rotor–stator molecular crystals of fullerenes with cubane
Nature Materials, 2005Cubane (C8H8) and fullerene (C60) are famous cage molecules with shapes of platonic or archimedean solids. Their remarkable chemical and solid-state properties have induced great scientific interest. Both materials form polymorphic crystals of molecules with variable orientational ordering.

Nanoemulsions produced by rotor–stator high speed stirring
International Journal of Pharmaceutics, 2015Nanoemulsions were produced by high speed stirring using an ART MICCRA D27 rotor-stator system. Nanoemulsions with a droplet size of 135 nm and a narrow size distribution were obtained. The emulsions are physically stable for at least three months. Optimized production parameters are a stirring speed of 36,000 rpm (maximum speed) and a production time ...

Turbulence Modeling for Rotor Stator Interaction Noise
16th AIAA/CEAS Aeroacoustics Conference, 2010The prediction of broadband rotor stator interaction noise produced by inhomogeneous turbulence is considered. The rigorous characterization of the turbulence, discussed previously by Glegg and Devenport (2001(b)), requires that it be specified in terms of the uncorrelated modes of the fluctuating velocity field.

Onset of turbulence in rotor–stator cavity flows
Journal of Fluid MechanicsNumerous studies have indicated that turbulence typically initiates along the boundary layer of the stationary disk within a rotor–stator cavity. To describe the transition process to turbulence on the stationary side of a closed rotor–stator cavity, a comprehensive approach combining global linear stability analysis with direct numerical simulation ...

Vane sweep effects on rotor/stator interaction noise
AIAA Journal, 1997The application of a lifting surface theory to compute the aerodynamic and acoustic response of swept vane stators to viscous rotor wakes is studied. Starting from the flow equations for a perturbed, axially subsonic flow, expressions are derived for the velocity field induced by a stator.
