The development of instability in a flow generated in a cylindrical cavity with a rotating endwall has been studied. Both possible scenarios of the development of instability, according to which the amplitude of velocity pulsation grows or decays with increasing twist of the flow, have been observed for the first time. It is established that these processes depend on the appearance of secondary perturbations and on their relative frequency.
