Studies on Three-Dimensional Boundary Layers on Bodies of Revolution. I. Nose Separation.

Abstract

The laminar boundary-layer development near the nose of a body of revolution and a two-dimensional airfoil is investigated until the onset of leading-edge separation. This is accomplished through the use of a coordinate transformation which eliminates any geometrical singularity at the nose in the governing boundary-layer equations. The resulting equations are examined by both asymptotic and numerical means. Comparable cases for the three-dimensional body of revolution and the two-dimensional airfoil are given and similarities as well as differences are discussed. (Author)
