Numerical Analysis of Acoustic Effect of Rotor Wakes in Rotor-Stator Interaction

Zusammenfassung:
A critical noise source in turbomachinery due to rotor-stator interaction is studied by the numerical solutions of Navier-Stokes equations. The two-dimensional unsteady flow equations are solved using an implicit upwind finite difference algorithm. A patched grid technique is applied in the multi-grid system. Non-reflecting boundary conditions are applied at inflow and outflow boundaries. It is found that the wake generated from the trailing edge of the upstream rotor has significant influence on the downstream stator row and the blade surface. The impingement of the rotor wake on the stator leading edge causes noticeable variations on the stator surface pressure distribution. Results of unsteady fluctuations of the flow field variables are presented in both rotating and stationary frames over several rotor passages.
