| Popis: | The purpose of this paper is to study the range of existence, the process of transition and the phase velocity of the spiral structure in an aspirated rotor–stator cavity. Experience shows that for a given flow rate and rotation, a whole range of azimuthal wave numbers are possible. Some are highly stable while others on the fringes of this range are subject to multiple transitions that depend on the fluctuations of the flow. Numerical simulation offers the advantage of enabling control over the wave number and the disturbance of the flow. Both approaches enable us to better understand the dynamics of this instability. |
