Calculation of unsteady rotor/stator interaction

21st Fluid Dynamics, Plasma Dynamics and Lasers Conference, 1990
Numerical simulations of unsteady multi-airfoil rotorlstator interactions are examined using the Unified Solution Algorithms (USA) code. The numerical results compare well with experimental data. The capability of the USA code to perform time-accurate calculations with moving grids is shown. Quasi-steady and unsteady solutions are discussed.

Motion Patterns at Rotor Stator Contact

Volume 1: 20th Biennial Conference on Mechanical Vibration and Noise, Parts A, B, and C, 2005
The present paper discusses the various movement patterns during rotor stator contact. Both rotor and stator are assumed to be flexible damped single degree of freedom systems. The contact is described by a flexible viscoelastic model. Dry friction between rotor and stator is taken into account.

Rotor - Stator Broadband Noise Prediction

14th AIAA/CEAS Aeroacoustics Conference (29th AIAA Aeroacoustics Conference), 2008
In this paper a semi analytic model for rotor - stator broadband noise is presented. The work can be split into two sections. The first examines the distortion of the rotor wake in mean swirling flow, downstream of the fan. Previous work by Cooper and Peake 4 is extended to include dissipative effects.

Grinding of Hexachloroethane in rotor–stator system

Южно-Сибирский научный вестник, 2022
Гексахлорэтан (ГХЭ) является малотоннажным продуктом и широко применяется в различных отраслях промышленности, в том числе пиротехнике и полимерной химии. Технические применения ГХЭ выдвигают определённые требования к его фракционному составу. По результатам обработки суспензии ГХЭ в роторно-пульсационном аппарате (РПА) получены образцы продукта с ...

Generation of sound by rotor-stator interaction

Journal of Sound and Vibration, 1970
Sound generation by rotor-stator interaction, which is the main cause of discrete frequency noise from subsonic compressor, is studied theoretically, taking into account the effect of compressibility of fluid. The combination of a single stator row and a single rotor row in a two-dimensional subsonic flow field is chosen as the interaction model, and ...

Parallel Computation of Rotor-Stator Interaction

1998
Numerical 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 ...

A Study of Unsteady Rotor–Stator Interactions

Journal of Turbomachinery, 1989
This work is concerned with simulations of rotor-generated unsteady response of the turbulent flow in a stator. The rotor’s effect is represented by moving cylinders of equivalent drag coefficient that produce passing wakes at the entrance of the stator.
