Abstract

Wind tunnel (WT) measurements for the validation of computational fluid dynamics (CFD) are essential to enable an accurate numerical assessment of complex indoor airflows in naturally-ventilated buildings. However, there is a lack of WT studies that employ realistic building geometries. The objective of this study is the validation of 3D steady Reynolds-averaged Navier–Stokes (RANS) simulations and scale-adaptive simulation (SAS) of cross-ventilation in a realistic building geometry using WT experiments. Therefore, velocities were measured in and around a cross-ventilated realistic building model with internal partitions by means of laser Doppler anemometry (LDA). The steady RANS simulations were conducted with the RLZ k-ε and SST k-ω turbulence models, whereas SAS was performed with the SST k-ω model. This study showed that the SAS significantly outperforms the steady RANS simulations.
