Multistep One-Way Nesting Scaling Approach to the Numerical Solution of Pedestrian Comfort-Related Wind Effects around a Tall Building
ABSTRACT
This work describes the application of a one-way nesting numerical method aimed at analyzing the pedestrian-level wind distribution around a tall building in addition to proposing and evaluating wind-mitigating barrier configurations. The implemented nesting procedure is termed "one-way" because it is assumed that the far-field boundary condition is dictated by the regional winds, regardless of the geometry of the site and its influence on the local fluid flow field. A consistent domain-reducing technique is used in order to achieve adequate domain discretization resolution without exceeding limited memory resources. The evaluation of the existing configuration and the consolidation of different mitigation configurations are accomplished through numerical experimentation before actual wind tunnel tests are carried out. The number of configurations to be tested in the wind tunnel is therefore reduced. Expected mitigation results for some of the areas under analysis are presented in detail.
