Computational fluid dynamics for cross‐ventilated airflow in an urban building

In this study, the velocity field in a naturally ventilated building within an urban-like array was explored using large-eddy simulations. Reduced-scale models were used to examine impacts of geometric conditions surrounding buildings and cross-ventilating windows on flow statistics instantaneous fields sheltered building. The components averaged opening area calculated for each condition arrays openings. results indicate that urban geometry significantly affects turbulent velocities. Additionally, three-dimensional distributions target clearly demonstrate considerable differences under different conditions. Such also affect mean, maximum, minimum wind speeds indoor regions. Moreover, two-point correlation coefficient (defined by velocities normal at center windward inside building) compared condition. strong correlations near two openings generated is important factor determining statistical features ventilating airflows.
