    The paper is based on authors‘a earlier model of synthetic jets – in the form of a set of simple ordinary differential equations for similarity-transformed quantities. The solution depends on a dimensionless parameter evaluated from experimental data. In contrast to analogous situation in similarity solutions of other shear flows, the parameter instead of being a constant was found to vary along the jet. Experients also show there are two distinctly different regions with clearly recognisable transition.The region downstream from the transition exhibits turbulence structure similar – but not identical – to those of steady jets.
