Thermal Modeling of a Mini Rotor-Stator System [PDF]
Volume 9: Heat Transfer, Fluid Flows, and Thermal Systems, Parts A, B and C, 2009 In this study the temperature increase and heat dissipation in the air gap of a cylindrical mini rotor stator system has been analyzed. A simple thermal model based on lumped parameter thermal networks has been developed. With this model the temperature dependent air properties for the fluid-rotor interaction models have been calculated.

On the transient behaviour of a laminar rotor–stator cavity [PDF]
Journal of Fluid Mechanics, 2018 The unsteady laminar flow between two large rotating disks when one of them is impulsively started is described using the von Kármán similarity analysis to reduce the solution of the Navier–Stokes equations to a set of ordinary differential equations. It is found that the transient phenomenon consists of three distinct phases.

Assessment of 3D modeling for rotor–stator contact simulations [PDF]
Journal of Sound and Vibration, 2015 Most often the dynamic analysis of rotor-to-stator rub is performed using 1D models. This leads to a small computational cost, but the reliability of the results is difficult to assess. This research work compares and analyzes the results of 1D and 3D rotor-stator contact problems, for different contact conditions more and less severe.

Impulsive Control of the Rotor-Stator Rub Based on Phase Characteristic
Abstract and Applied Analysis, 2014 An impulsive control method is proposed to eliminate the rotor-stator rubbing based on the phase characteristic. The relation between the vibration energy and the phase difference suggests the starting point for controlling the rotor-stator rubbing by ...
