Preliminary Experiment Designed to Support a Feasibility Demonstration of a Novel Method for Developing Unsteady Boundary Layer Profiles.

Abstract

The feasibility of a new experimental technique for studying the effect of unsteady flows on boundary layers is under development. The method studied uses a stationary NACA 0012 airfoil in a steady subsonic wind tunnel. Unsteadiness in the flow over the airfoil would be generated by an unsteady external aerodynamic interference. Initial results are reported in which upwash effects of stationary cylinders of several sizes located at different positions downstream and below the airfoil are measured. The position for maximum influence is determined. (Author)
