Introduction

The analysis of turbomachinery often involves the examination of the transient effects due to flow interaction between the stationary components and the rotating blades. In this tutorial, the sliding mesh capability of ANSYS FLUENT is used to analyze the transient flow in an axial compressor stage. The rotor-stator interaction is modeled by allowing the mesh associated with the rotor blade row to rotate relative to the stationary mesh associated with the stator blade row.

This tutorial demonstrates how to do the following:

• Create periodic zones.

• Set up the transient solver and cell zone and boundary conditions for a sliding mesh simulation.

• Set up the mesh interfaces for a periodic sliding mesh model.

• Sample the time-dependent data and view the mean value.
