Relaminarization of turbulent puffs in pipe flow
Basheer A. Khan, Shai Arogeti, Oriel Shoshani +1
This study examines the relaminarization of turbulent puffs in pipe flow using highly resolved direct numerical simulations at Reynolds numbers of 1880, 1900, and 1920. The exponen…
Non-Exponential Relaxation in the Rotating Frame of a Driven Nanomechanical Mode
Hyunjin Choi, Oriel Shoshani, Ryundon Kim +6
We present direct observation of the ring-down dynamics in the rotating frame of a resonantly driven single-mode nonlinear nanomechanical resonator. An additional close to resonanc…
Saddle-node bifurcation during the relaminarization of turbulent puffs in pipe
Basheer Ahmad Khan, Shai Arogeti, Oriel Shoshani +1
Turbulent puffs in a pipe persist for a long time before abruptly transitioning to laminar flow through viscous exponential decay. Direct numerical simulation results reveal a sadd…
