Flow over complex terrain estimated by a general purpose Navier-Stokes solver

Abstract

A general purpose Navier Stokes solver has been applied to atmospheric flow on microscale. For flat terrain the model produces the well known logarithmic profile in the surface layer and describes the effect of roughness change. At Askervein Hill, good agreement between model results and measurements is observed also behind the hilltop, where linearized models overpredict the wind speed.
