A 2D CFD Study of Symmetrical Airfoils PART II: in Cascade Flow

摘要

This paper deals with the application of Computational Fluid Dynamics (CFD) to the analysis of the aerodynamic characteristics of symmetrical airfoil blades in 2-Dimensional cascade flow. The model was used to compare a proposed blade profile of the Wells Turbine with the NACA 0015 blade by analysing the aerodynamic forces and the compressibility effects. The objective is to increase the working angle of attack range by postpoing the compressibility effects. This proposed profile was analysed as inviscid flow at the same settings as the NACA 0015 blade. The paper presents the results of the numerical investigation, while the differences in the profile geometry and the resulting differences in the blade characteristics are also discussed.
