Abstract

An experimental investigation is conducted to determine the effect of low-frequency mean flow unsteadiness on the characteristics of a plane wake. Complex demodulation and bispectral analysis techniques are used to obtain quantitative measurements of the modulation and coupling mechanism generated by the mean flow unsteadiness. The results show that low-frequency mean flow unsteadiness increases the amplitude and phase modulation levels of the frequency components that correspond to the vortex street.
