SOLUTION-ADAPTIVE STRUCTURED-UNSTRUCTURED GRID METHOD FOR UNSTEADY TURBOMACHINERY ANALYSIS .2. RESULTS

A solution-adaptive method for the time-accurate analysis of two-dimen sional flows in multistage turbomachinery is presented. The method emp loys a hybrid structured-unstructured zonal grid topology in conjuncti on with appropriate modeling equations and solution techniques in each zone, thus combining the advantages of both structured and unstructur ed grid methods. An efficient and robust grid adaptation strategy is a lso used for the unstructured grid regions. The numerical methodology is presented in detail in Part I of this article. Results obtained usi ng this method for different turbomachine flow configurations are pres ented in this article. The numerical results compare well with availab le experimental data and other structured grid based simulations.
