Abstract

Flow over complex terrain and hills is a concern in many research areas such as determination of air pollution zones, predictions of smoke movement from forest fires, wind energy assessment and siting of wind energy converting systems (WECS). It can be examined by means of field studies, theoretical analysis, wind tunnel simulation and numerical modelling. Concerning numerical modelling of flow over hills, a problem is scaling up the unresolved effects of flow interactions with the fine-scale topography and combining this in regional or global scale models, [2]. Linear models, such as WAsP, are not valid for steep terrain, due to the closure assumptions in separation areas. It is still a challenge for computer modellers to determine recirculation zones in high resolution models such as Reynolds Averaged Navier-Stokes (RANS) or large-eddy simulation (LES), [25].
