### Author M. Manna, Andrea Vacca, Roberto VerziccoPublish Year 2020Laminarturbulent transition in a slowly pulsating pipe flow

Transitional pulsating flow in a pipe is investigated experimentally in the frequency region where its behavior is assumed to be quasisteady. Instantaneous velocity measurements were performed at several radial locations at the exit plane of the pipe. The output of flushmounted hot wires at two upstream positions was also recorded simultaneously. The results indicate that the quasisteady Pulsating flow in a pipe Journal of Fluid Mechanics Chaotic oscillations in pipes conveying pulsating fluid Pulsating flow in a pipe Journal of Fluid Mechanics Chaotic motions of a simply supported nonlinear pipe conveying fluid with harmonie velocity fluetuations are investigated. The motions are investigated in two flow velocity regimes, one below and above the critical velocity for divergence. Analyses are carried out taking into account single mode and two mode approximations in the neighbourhood of fundamental resonance.
