PARAMETRIC INVESTIGATIONS OF THE EFFECT OF ICING ON THE AERODYNAMIC CHARACTERISTICS OF A WING AIRFOIL

ABSTRACT

Presented in this article are the results of computational investigations of the influence of shape and thickness of ice at the leading edge of a straight wing airfoil on the flow of viscous uncompressible liquid over the wing. The influence of airfoil shape on the aerodynamic characteristics in the presence of ice growth at the leading edge is considered. The computation is fulfilled using the solution program of Navier-Stokes equations averaged by Reynolds numbers.
