Seven RANS models (Spalart-Allmaras, k-epsilon, k-omega; and their variants, Reynolds Stress Model (RSM)), DES-SST and LES model have been used to predict the pressure coefficient (Cp) distribution on a cube and the Cp difference of a canopy in an atmospheric boundary layer flow. The simulation results show that k-omega-SST gives the best prediction in both cases. The RSM also accurately predicts the Cp in the cube case. The k-omega-SST and DES-SST models have been used to simulate the wind load on flat roof mounted solar panels under similar flow conditions with different wind attack angles. The simulation results demonstrate that both k-omega-SST and DES-SST give good prediction of the drag force at all wind attack angles and reasonably good prediction of the lift force at most wind attack angles. The k-omega-SST model has also been used to investigate the change of wind load on solar panels with three different configurations.
