...Joshua Yen; Noor A. Ahmed A parametric study of the interaction between dynamic stall and a zero-net mass flux synthetic jet installed on a wing was investigated by identifying the dominant frequencies in the resulting flow field using spectral analysis. The instantaneous pressure distribution...

... in the wicket gates channels. The spectral analysis shows a rise of a low frequency component (about 70% of the impeller rotational frequency) at runaway, which further increases as the zero discharge condition is approached. Analysis of the instantaneous pressure peripheral distribution in the vaneless gap...
