CFD applications in structural wind engineering

Abstract

Computational Fluid Dynamics (CFD) is basically a numerical approach to simulating or predicting phenomena and quantities of a flow by solving the equations of motion of the fluid at a discrete set of points. CFD has greatly improved recently and has become an application tool for wind engineering problems. This paper first explains the characteristics of NS equations, and then describes in detail the discretization schemes, turbulence models, inflow turbulence and numerical procedures. Finally, it provides an example of calculation of strong wind in hilly area by utilizing Large Eddy Simulation.
