Influens of swirling on flow stability in channels

Akhmetov V. K.

The problem of hydrodynamic stability of a swirling flow of a viscous incompressible fluid in a channel with rigid walls is considered. The solution is determined by numerical integration of sixth-order ordinary differential equations system. The amplification coefficients and phase velocities of the most unstable disturbances are calculated for various flow profiles.

Keywords:hydrodynamic stability, swirling flow, viscous fluid, amplification coefficients.
