This chapter covers the fundamental concepts of flow simulation and modeling of physical processes. Due to the high Reynolds numbers in wind engineering, directly solving the Navier-Stokes equations for viscous flows is not possible, which is why turbulent processes must be modeled. The focus is on representing time-varying phenomena, with methods ranging from steady RANS approaches to the more computationally intensive LES methods, which offer a more realistic depiction of flow conditions.
