Rubbing Phenomena in Rotor-Stator Contact

Nonlinear Dynamics and Stochastic Mechanics, 2000
Abstract This paper discusses the vibration phenomena of a rotor rubbing with a stator caused by an initial perturbation. The analytical model consists of a simple disc-shaft rotor and a fixed stator. The perturbation is an instantaneous change of the radial velocity when the rotor is rotating in its normal steady state. It is found that

Centrifugal Flow in a Rotor-Stator Cavity

Journal of Fluids Engineering, 2005
The present work considers the turbulent flow inside an annular rotor-stator cavity with and without centrifugal throughflow. Extensive measurements performed using a two-component laser-Doppler anemometer technique, and pressure transducers are compared to numerical predictions based on one-point statistical modeling using a low-Reynolds-number second-

Turbine Rotor-Stator Interaction

Journal of Engineering for Power, 1982
The aerodynamic interaction between the rotor and stator airfoils of a large scale axial turbine stage have been studied experimentally. The data included measurements of the time averaged and instantaneous surface pressures and surface thin film gage output on both the rotor and stator at midspan.

Foamability of Silica Suspensions in a Rotor-Stator Mixer

Textile Research Journal, 1994
A procedure is described for making aqueous silica suspensions with a desired particle size distribution. The influence of silica particles in different concentrations on foam ability in a rotor-stator mixer for different rotational speeds has been studied by means of mixing characteristics.

Windage Heating in a Shrouded Rotor-Stator System

Journal of Engineering for Gas Turbines and Power, 2014
This 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.

Multistage rotor‐stator spinning disc reactor

AIChE Journal, 2011
AbstractThe scale up of a rotor‐stator spinning disc reactor by stacking single stage rotor‐stator units in series is demonstrated. The gas‐liquid mass transfer per stage is equal to the mass transfer in a single stage spinning disc reactor. The pressure drop per stage increases with increasing rotational disc speed and liquid flow rate.

Rotor–stator molecular crystals of fullerenes with cubane

Nature Materials, 2005
Cubane (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.

An analysis of rotor-stator interaction

2012
The 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-

Onset of turbulence in rotor–stator cavity flows

Journal of Fluid Mechanics
Numerous 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 ...

LES of open rotor–stator flow

International Journal of Heat and Fluid Flow, 2006
Abstract Computer experiments (LES) of the axisymmetric and statistically steady turbulent flow between a rotating and a fixed disk have been performed. This flow is a representative of the flow in an unshrouded rotor–stator configuration. The flow is characterized only by a local Reynolds number and a local gap ratio, provided that the distance from
