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

JAPAN ARCHITECTURAL REVIEW, 2022
AbstractIn this study, the velocity field in a naturally ventilated building within an urban‐like array was explored using large‐eddy simulations. Reduced‐scale building models were used to examine the impacts of the geometric conditions in the surrounding buildings and cross‐ventilating windows on the flow statistics and instantaneous velocity fields ...
