Aerodynamic characteristics and flow field characteristics of rigid and forced-vibration square cylinders in turbulent flow

Fluid–structure interaction (FSI) is a fundamental problem in fluid mechanics, which is prevalent across diverse practical engineering applications and has a significant impact on the safety and reliability of structures. In this study, large eddy simulation is employed to perform numerical simulations of a three-dimensional finite-length isolated square cylinder under varying incoming flow velocities and prescribed crosswind vibration states in a turbulent inflow. This configuration, combining finite-length structure, structural vibration, and turbulent flow, is designed to closely mimic realistic wind-resistant conditions encountered in engineering practice. Based on the mean pressure coefficients and flow…
