A platform for research: civil engineering, architecture and urbanism
This chapter first introduces the fundamentals of CFD, which includes the governing equations, turbulence models, numerical methods, grid generations, boundary conditions and computational algorithms. Since wind effects on long‐span cable‐supported bridges is a topic in this book, the applications of CFD to obtain aerodynamic (force) coefficients of a bridge deck, a vehicle on ground and a vehicle on the bridge deck are illustrated, and the obtained results are validated through comparisons with wind tunnel results. The use of CFD to estimate flutter derivatives of a bridge deck is then presented, and the non‐linear aerodynamic forces on a bridge deck with a large oscillation amplitude is finally explored using CFD.
