Abstract
A two-dimensional model was developed and used in a preliminary investigation of the relationship between flow oscillation frequency, oscillation amplitude, and turbulent boundary layer separation in a low speed, oscillating wind tunnel.
It was found that the frequency of oscillation had a profound effect upon the amplitude of oscillation and flow separation. Frequencies from 20 Hz to 28 Hz and 70 Hz to 80 Hz allowed attachment of the boundary layer, while other frequencies, up to 100 Hz, caused flow separation in eighteen degree divergent section.
