| Abstract: | Gas flow behavior near the laminar-turbulent transition condition in a pipe with a divergent inlet section has been studied
experimentally. Hysteresis in the laminar-turbulent transition regime is observed. Also, we have observed unstable, regular
vacillation of the flow rate when the time-averaged flow is controlled at the laminar-turbulent critical point with stationary
background conditions.
