Datasets for ­­­"Numerical Prediction of Two-Dimensional Coupled Galloping and Vortex-Induced Vibration of Square Cylinders Under Symmetric/Asymmetric Flow Orientations"

This study presents an advanced numerical model for predicting a two-dimensional coupled galloping and vortex-induced vibration (VIV) in cross-flow and in-line directions of square cylinders under symmetric and asymmetric flow orientations. The present model combines the quasi-steady theory for the galloping with the nonlinear structure-wake oscillators simulating VIV, capturing the time-varying drag and lift hydrodynamic forces with the time-averaged and fluctuating components.

本研究提出了一种预测二维耦合跳跃与涡激振动（VIV）的先进数值模型，该模型针对方形圆柱在横流和同流向下的对称与非对称流动方向。本模型将跳跃的准稳态理论与非线性结构尾流振荡器相结合，以模拟涡激振动，同时捕捉时间变化的阻力和升力的水动力，包括时间平均值和波动成分。
