Abstract : A computational method for determination of aerodynamic characteristics of airfoil cascades subjected to viscous flow is presented. This method is based on the determination of the flux perturbation directly due to the local continuous stream velocity over energy single cascades airfoil. Particular attention is given to the development of a method suitable to decrease automatic computation time and, at the same time, to make possible versatile application to physical phenomena simulation. Various comparisons with theoretical and experimental values carried out by other authors confirm the validity of the present method.
