The CAARC building is a validation case that has for many years been used to validate CFD codes. This case has been shown in the past validating both URANS and LES turbulence models, where the trend has been that RANS/URANS has predicted the windward facade well but not predicted the sides and Leeward facades. In contrast, LES has shown a good agreement with experimental results, however, there is still in general, an over-prediction for the sides and leeward facade, and a worse prediction on the windward facade. In this project we look at SimScales LBM implementation, PaceFish from Numeric Systems, and how well it performs using Hybrid models, K-omega SST DDES, and k-omega SST IDDES models. These models use wall models based upon K-omega SST but then transition to the highly accurate LES model further from the wall. - Copy
