Abstract
Recently, two new test cases have been proposed for benchmarking of numerical and physical modelling of complex terrain flows, these are the Alaiz test case (see Conan et al., 2011) and the Bolund experiment (see Bechmann et al., 2009). The Bolund experiment was initiated by Ris? DTU as a blind comparison of different numerical models (including linear, RANS and LES simplifications of Navier-Stokes equations). More detailed description of the blind comparison can be found in Bechmann et al (2009). The main conclusions from the initial analysis are: a) a great scatter of the numerical results exist (mainly in the vicinity of the island escarpment, b) the mean velocities are better predicted than turbulent kinetic energy (TKE), and c) the best models predicting both, mean wind speed and TKE are the RANS models with two closure equations.
