Visualization and Parametric Study on Vortex Shedding Suppression of Cylindrical Structures in Offshore Engineering Using Large Eddy Simulation

Journal of Marine Science and Engineering, 2023
Cylindrical structures are widely used in offshore and marine engineering, but they may suffer from vortex-induced vibration under the influence of ocean or wave currents, which can lead to severe fatigue damage. In this study, we applied the open-source

Vortex-Induced Vibration Performance Analysis of Long-Span Sea-Crossing Bridges Using Unsupervised Clustering

Journal of Marine Science and Engineering
Vortex-induced vibration is a type of wind-induced vibration occurring frequently in large-span sea-crossing bridges under relatively low wind speeds, posing a threat to the structural fatigue performance and driving comfort.

The galloping of a 4:1 rectangular cylinder at Re = 300

AIP Advances, 2023
The flow-induced vibration (FIV) of a rectangular cylinder with a side ratio of 4 at Re = 300 is numerically investigated by a two-dimensional spectral-element method. The cylinder is constrained to vibrate only in the cross-flow direction.

A Practical Noise2Noise Denoising Pipeline for High‐Throughput Raman Spectroscopy

Advanced Engineering Materials, EarlyView.
A lightweight and reproducible denoising pipeline for high‐throughput Raman spectroscopy is introduced, based on a 1D convolutional autoencoder trained with a Noise2Noise strategy. Using only repeated short‐exposure acquisitions, the method suppresses stochastic noise without reference spectra, enabling reliable spectral reconstruction while preserving

Investigation of the motion characteristics for a long flexible rotating pipe in flow by IDVM–FEM method

AIP Advances, 2021
A long flexible rotating pipe in flow is investigated by using an improved discrete vortex method and finite element method. For the pipe without rotation, the lock-in phenomenon has been confirmed and discussed and the motion characteristics are ...
