Numerical Analysis of the Unsteady Rotor-Stator Interaction in a Low Pressure Centrifugal Compressor by Using Adamczyk and Proper Orthogonal Decompositions

摘要

The aim of this paper is to study the unsteady rotor-stator interaction in a low pressure centrifugal compressor using the finite volume method to solve the Unsteady Reynolds-Averaged Navier-Stokes (URANS) equations. In order to understand better, the rotor-stator interaction, the unsteady results are processed using both Adamczyk decomposition and Proper Orthogonal Decomposition (POD). Both decompositions show the behavior of unsteady rotor-stator interaction but the POD modes also show the numerical errors.
