Unsteady Flow Over Aerofoils with Separation.

Abstract

The mean and fluctuating components of surface pressure and lift have been measured on a NACA 0012 aerofoil in an unsteady flow gust tunnel giving a mean flow with streamwise fluctuations of variable amplitude and frequency. The tests were carried out for a range of aerofoil incidences from 10 deg (attached flow) to 20 deg (separated flow) at mean chord Reynolds number of 1.2 x 105. Some comparisons of the results are made with unsteady aerofoil theory.
