In pipes, both laminar and turbulent flows can in principle exist and be stable, but already a small disturbance can make a laminar flow turbulent.

The linear stability of confined, periodic, parallel fluid flows is examined. The flow fields considered consist of a steady pressure gradient-driven velocity field combined with a purely oscillatory ...
