Pipeline Integrity at Risk: Understanding Vibration and Scour in Unsteady Flows

A suspended pipeline on an erodible bed does not fail all at once; it fails through a quiet accumulation of vibration and scour, each cycle eroding the margins of safety. Our experimental work shows that the clearance ratio, not just the flow rate, governs this process. As \( e_0/D \) crosses from 0.8 to 1.2, the cross-flow amplitude surges by 76% while the in-line response lags, revealing a partial decoupling that challenges steady-flow assumptions. This selective amplification, coupled with a frequency lock near 2.
