Abstract Experimental investigations of Laval nozzle flow show for relatively low supply to exit pressure ratios, which correspond to shock wave positions close to the nozzle throat, three different, oscillatory instabilities. (i) Shock pattern oscillations where the root of a λ-like shock front remains nearly in constant position, but where the proportion between the normal part and the oblique part of the shock changes periodically. (ii) Shock wave and separation bubble oscillations where the motion of the shock wave is accompanied by displacements of the separation bubble. (iii) Flow rate oscillations where the shock waves leave periodically through the nozzle throat in upstream direction.
