VALIDATION OF A COMPUTATIONAL FLUID DYNAMICS METHOD TO BE APPLIED TO LINEAR CASCADES OF TWISTED-SWEPT BLADES

Abstract

A synthetic method has been elaborated for the validation of a Computational Fluid Dynamics tool developed for the future investigation of the combined aerodynamic effects of sweep and spanwise changing stagger angle on stationary linear blade cascades. The validation method is based on specially selected experimental data available in the open technical literature. The capabilities of the CFD method for resolution of near-endwall phenomena due to sweep as well as of the effect of changing incidence were tested. The CFD methodology and the experimental validation process have been documented herein in accordance with the requirements regarding industrial CFD tools.
