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.

本研究提出了一种先进数值模型，用于预测方柱在对称与非对称来流工况下，横流向与顺流向的二维耦合驰振与涡激振动（vortex-induced vibration, VIV）。该模型将用于驰振的准稳态理论与模拟涡激振动的非线性结构-尾流振子相结合，可捕捉包含时均与脉动分量的时变阻力及升力气动力载荷。
